25 Method for starting a power loom US09535276 2000-03-24 US06307340B1 2001-10-23 Arno Wagner; Herbert Mueller
A main drive shaft of a power loom reaches the rated operating rpm of the loom by the time of the first beat-up of the reed, thus avoiding start-up faults in the fabric. A flywheel mass is accelerated to a start-up rpm that is higher than the rated operating rpm before it is coupled with the main drive shaft. The start-up rpm is determined automatically and iteratively, with ever-increasing accuracy in successive starts of the loom. When the main drive shaft is coupled to the flywheel mass, the flywheel mass rpm decreases simultaneously as the main drive shaft rpm increases from standstill to the operating rpm. The actual main drive shaft rpm is measured at least at the time of the first beat-up and any deviation from the rated operating rpm is evaluated by the loom control. After each start-up, a new data set is generated based on the measured values and is used to calculate an updated or modified flywheel start-up rpm in the next start-up operation so that the main drive shaft more accurately reaches at least the rated operating rpm by the time of the first beat-up of the reed.
26 Method and apparatus for temporarily activating a brake in a weaving loom US544844 2000-04-06 US6164340A 2000-12-26 Valentin Krumm
The brake components of a clutch brake combination in an automatic high speed loom are periodically cleaned to avoid delays in the brake action that occur following a prolonged loom operation without a stopping. The stopping signal is either derived from randomly occurring events or criteria such as a weft breakage or similar criteria on the one hand, or when a criterium stored in the memory or program of the loom control occurs. The respective control signal is generated in response to whichever criterium occurs first.
27 Electronic fast-starting system, particularly suitable for an air loom US362869 1994-12-23 US5729114A 1998-03-17 Gianluigi Sora; Ruggero Manzardo; Vittorio Apolloni; Lucio Sardella
An electronic fast-starting system for a textile loom in which an asynchronous driving motor, whose phase windings are triangularly connected, is mechanically connected to the main crank shaft of the loom and is controlled by an inverter/controller receiving not only the set speed value but also the outlet signal of a speed detector situated on the main crank shaft.
28 Method of restarting a loom after stoppage US49937 1993-04-20 US5335698A 1994-08-09 Klaus Berktold; Kurt Gunther; Anton Egloff
A method of restarting a loom after an interruption in the weaving process. A cloth fell (15) is moved from an operative or beating position (15) to a second position (15') away from a sley (4). The weft yarn is prevented from being fed into a shed (20) and the loom is then driven in a idling motion for a number of weaving cycles. A shed forming motion 3 and at least one of the warp let-off motion 10 and the cloth take-up motion 12 are driven independently of the predetermined weaving program. When the loom has reached its original dynamic operative state and the warp threads are at the original operative tension, the cloth fell is advanced to the beating position of the sley and the loom is restarted according to the predetermined weaving program. This method prevents visible points of start from occurring in the fabric because of the interruption in the weaving process.
29 Weaving bar prevention in a jet loom US790573 1991-11-08 US5224520A 1993-07-06 Masami Shinbara; Fumio Yasuoka
Upon slow operation of a loom, a feed-out motor for a warp beam or a wind-up motor for a surface roller is driven to thereby displace a cloth fell of woven fabric from a normal position toward the fabric, and upon completion of the slow operation, the motor is driven reversely to allow the cloth fell to ressume the normal position. The cloth fell is thereby prevented from being beaten by a reed while protecting woven fabric from generation of weaving bar. Suppression of the weaving bar can also be realized by varying warp tension or a one-shot weft insertion performed from a main weft inserting nozzle while causing auxiliary nozzles to previously produce jets simultaneously or in relays.
30 Method and system for starting a power loom US136656 1987-12-22 US4837485A 1989-06-06 Klaus Meroth; Dieter Wegendt-Kristyn
A power loom is started by first accelerating a flywheel mass to an r.p.m. higher than a rated operational r.p.m. of a loom drive shaft while the flywheel mass is disconnected from the loom drive shaft but connected to the loom drive motor which is operated at a higher r.p.m. than the rated operational r.p.m. Then, the flywheel mass is connected to the loom drive shaft while the loom drive motor is disconnected from its power supply so that only the energy stored in the accelerated flywheel mass accelerates the loom drive shaft to its rated r.p.m. Then, after the first beat of the reed the drive motor is electrically reconnected to its power supply for driving the loom at the rated r.p.m. The motor may be operated at a higher r.p.m. e.g., through a frequency converter or by switching a multipole motor from a higher pole number, e.g., four poles to a lower pole number, e.g. two poles, whereby the motor operation at the higher pole number with a lower r.p.m. corresponds to the rated operational r.p.m. The pole switch-over takes place with such a delay that the full higher r.p.m. is not reached.
31 Weft-bar (set mark) prevention system for a loom US428666 1982-09-29 US4480665A 1984-11-06 Shuichiro Imamura; Akira Arakawa
A weft-bar (set mark) prevention system for a loom which can prevent a weft-bar caused when the loom is immediately restarted, after the loom has been stopped due to weft- or warp-thread cut (i.e., breakage of a weft or warp thread). When the loom is restarted from the closed-shed state, a greater additional warp tension is applied to the warp threads; when the loom is started from the open-shed state, a smaller additional warp tension is applied to the warp threads. After one or two cycles of the loom motion, the above-mentioned additional warp tensions are not applied, because the main motor is in a stable condition. The system according to the present invention comprises an optical loom-starting angle sensor for detecting whether the loom is started from the closed-shed or open-shed, a counter for determining at least one initial cycle during which warp tension is controlled, air cylinder to push the easing lever in the direction to increase warp tension.
32 Start mark preventer for looms US92591 1979-11-08 US4245676A 1981-01-20 Ralph H. Brown
An improved start mark preventer for looms formed by a manually operable device including a double armed lever having a control handle mounted on one arm and a control pawl on the other arm. The control pawl is disposed in operative engagement with the loom's ratchet wheel which rotates its take-up roll by means of a feed pawl and hold-back pawl. The device includes a guide for the control handle with selectively positionable stop members that provide a neutral, first and second positions for the handle. Movement of the handle to the first position moves the fell forwardly of the reed's beat-up position, in the second position the fell is permitted to return to its initial position and upon starting the loom the control handle will automatically move to its neutral position.

38 Method for Operating a Projectile Loom US11920792 2006-05-17 US20090101227A1 2009-04-23 Valentin Krumm
It is the object of the invention to avoid weaving defects, which due to a starting process of a projectile weaving machine in fabrics, especially such with ground weaves, as a cause of the starting process. The object is achieved according to the invention in that the projectile weaving machine is operated in the slow speed running after each starting process during the first weaving cycle, in that during the slow speed running the weft thread is inserted with a velocity adequate for the prescribed operating rotational speed, and in that the projectile weaving machine is operated with the prescribed operating rotational speed directly after the end of the first weaving cycle.
39 Method and weaving machine for monitoring the fell position following weaving operation interuption US397530 1995-03-01 US5520224A 1996-05-28 Godert De Jager
The position of the fell of a cloth being woven on a weaving machine is sensed with a sensor needle that can be moved into and out of the cloth at a location proximate the fell during interruption of the weaving operation. Upon insertion of the sensor needle into the cloth, it moves with the cloth and therewith measures cloth displacement while the weaving machine is at rest. The sensor needle is attached to an actuation device capable of reciprocating the needle into and out of the cloth. The sensor needle is inductively coupled to a distance sensor which measures the needle displacement and therewith the displacement of the fell. In this manner, fell displacements caused, for example, by such factors as the relaxation of the run of cloth or of the warp yarn while the weaving machine is at rest can be measured and, before weaving is restarted, the position of the cloth, and therewith of the fell, can be corrected.
40 Warp yarn leveling motion incorporated with a loom stop timing judging device US228424 1994-04-15 US5467801A 1995-11-21 Kazuo Kaneda; Masayuki Ushiro
A loom equipped with a leveling motion incorporated with a cam-operated type shedding motion. The loom is provided with a control unit to control a variety of operations of the loom. Upon stopping of the loom weaving operation in response to a loom stop signal, the control unit judges that a loom stop time required for recovering a failed condition is longer or shorter than a predetermined time in accordance with the type of the loom stop signal which is different depending upon the cause for which the loom weaving operation is stopped. If the result of the judgement is that the loom stop time is longer than the predetermined time, the leveling motion is operated to level warp yarns at the level near a warp line, thereby loosening the tension applied to the warp yarns.
