61 Fabric monitoring means for power looms US658042 1984-10-05 US4582095A 1986-04-15 Rolf Kronholm
A power loom for the manufacture of woven fabrics, in particular woven wire fabrics and felts for use in papermaking machines, is provided with a computerized pattern recognition system for monitoring the warp, the fabric, the edge of the fabric, the density of the weft, and so on. The device includes a video camera and computerized image processing means. By analyzing a picture taken near an edge of the fabric, digital information concerning the position of the edge of the fabric, the weft density, and so on, can be obtained. The digital information is adapted to be used in an open or closed control system for positioning the edge of the fabric in correct position, after an interruption of fabric through the loom, before a restart of the fabric feed. Digital information concerning the actual weft density can be utilized as the actual value in a weft density control system using the driving means of the warp beam of the loom as the executive members via a tensile stress control applied to the fabric.
62 Method for starting the operation of a loom US583058 1984-02-23 US4564050A 1986-01-14 Hideo Hirano
A method for starting the operation of a loom always under a constant warp tension after the completion of the amendment of faults in the woven fabric such as miss-pick. A warp beam in the stationary loom is rotated by a commmand signal from a control unit in the normal or reverse direction so that the preset tension can be attained. As a result, a weaving bar which often occurs in the prior art just after the loom has restarted due to disturbance of gear ratio of the speed changer during the transient state can be avoided.
63 Relief means for the drive mechanisms of components alternatingly rocking between two end positions US530009 1983-09-07 US4546803A 1985-10-15 Peter Dornier
This system is intended for relieving the drives of weaving machine components alternatingly rocking between two end positions, for instance a first rocking member forming a gripper rod drive and a second rocking member forming a reed drive. A common energy storing device, for instance a spring, is connected with the two separate drive units, so that each end of the spring is connected to one of the two separate rocking members. The rocking motions of the two rocking drive members do not overlap in time.

Method of starting up a loom at a first warp tension, which is different from a second warp tension, comprises the storage of both tension values in a control unit, the detection of actual warp tension before starting by comparing actual tension with the first warp tension, and the function of independently rotating the warp beam to correct any variation between the two tensions By above, the starting tension is established. Loom operation is then controlled, after starting, to establish the running warp tension.

A system for preventing weft stripes from occurring in a loom at start-up, e.g. after stoppage due to warp or weft breakage, comprises a loom starting-angle detector that transmits a corresponding signal to a warp tension-increasing mechanism, (3,6,33-37) which applies greater-than-normal tension to the warps(2) according to the loom angle at start-up for at least one initial loom cycle. The warp tension is increased by a warpengaging guide that is operated by an air cylinder controlled by an electromagnetic valve. Weft-bar fabric markings are avoided after loom stoppages for repairs.
75 METHOD FOR OPERATING A WEAVING AND SHEDDING MACHINE PCT/DE0103840 2001-10-06 WO0234982A3 2003-05-08 KRUMM VALENTIN; VON ZWEHL DIETMAR; LEHMANN MICHAEL; MAYER DIETER
The aim of the invention is to optimize the electromotive driving torques and braking torques required in the starting and braking phase of the weaving and shedding machine while reducing the mechanical stress on machine elements of the weaving and shedding machine and while preventing starting marks in the fabric, and based on this, to obtain so-called soft starts and soft stops, in particular, of the shedding machine. To this end, the invention provides that, in a weaving machine equipped with an electromotive main drive and in a shedding machine equipped with an electromotive auxiliary drive, the shedding machine is started at a time t1 that occurs before the starting time of the weaving machine. In addition, the invention provides that in the instance of an activated interruption of the weaving process, the shedding machine comes to a stop at a time t5 that occurs after the stop time t4 of the weaving machine.
