| 61 | Leather perching machine | EP01109619.5 | 2001-04-18 | EP1148144A3 | 2001-12-19 | Polato, Antonio |
An improved perching machine, in particular for softening and stretching industrial hides or the like, comprises at least one first section (5) and at least one second section (5') operationally coupled and located downstream of the first section; each section (5; 5') is formed by at least one pair of mutually facing conveyor belts (6, 7; 6', 7') for retaining and conveying the hides (P) and by at least one pair of plates (10, 12; 11, 13; 10', 12'; 11', 13') substantially parallel to the belts (6, 7; 6', 7') and acting on opposite sides thereof for softening and stretching the hides. The pair of conveyor belts (6', 7') of the downstream section has a feed speed (V') greater than that (V) of the pair of belts (6, 7) of the upstream section (5). Each section (5; 5') comprises independent motors (20, 20') operating a respective pair of conveyor belts (6, 7; 6', 7') so as to impart varied speeds (V', V) thereto. The ratio (V'/V) between the feed speed of the pair of belts of the downstream section and the speed of the pair of conveyor belts of the upstream section is between 1 and 4 and preferably equal to about 1.2. The advantage of exerting a greater stretching force on the hides in the longitudinal direction when passing from one section to the next one is obtained. |

The perching process comprises a stage of continuous progress of the leather to be treated, a stage of stretching the leather at several spots of its surface by forcing it by means of pegs to penetrate the holes of a counter-plate and a stage of relaxation of the leather due to the withdrawal of the pegs from the stretching holes, wherein during the stretching stage a simultaneous smoothing operation on the leather surface occurs thanks to the translation of the pegs within the stretching holes. The perching machine carrying out said process comprises a plurality of plates with pegs (7) each counterposed to a counterplate (11) presenting holes (12), into which the leather (20) is forced to penetrate by the vertical action exerted by the pegs (9) attached to the top of the plates with pegs (7).

| This invention relates to apparatus for working flat, flexible material by means of working members opposing each other. One of the working members is driven back and forth toward and away from the other working member. A piston to which the other working member is connected, is subject to a pressure from a pump and subject to a reset force whereby the piston may be adjusted to predetermined starting elevational positions to provide a desired working pressure. A pressure relief valve assures that the piston yields when the working pressure exceeds said desired pressure and returns to said starting position when the working pressure is reduced again. In a further embodiment an auxiliary pressure space of selectively variable volume is provided for adjusting said piston to different elevational starting positions even during the operation of the apparatus.
