Abstract (en)
[origin: EP0505666A1] Apparatus for mechanically rolling leather onto a support sleeve, comprising a stand (1), rolls journalled in the stand, an endless web (4) which extends over the stand rolls, and web drive-rolls (5, 7). The web (4) is intended to be moved in between two further rolls (12, 25) located at different heights, by means of the rollers (10) acting on opposite edges of the web, such as to form a pocket or hollow. Placed in the pocket is a sleeve around which the leather is intended to be wound by the web a desired number of turns in a fold-free and smooth fashion. The upper pocket-forming roll (12) is raised when rolling of the leather onto the cylinder is completed, and the finished leather roll is removed from the pocket, so as to enable the roll to be lifted by gripping devices (17) forming part of a traversing lifting device (16) movable across the web. The speed at which the machine drive devices operate is controlled, and the various part operations can be controlled individually and sequentially with respect to time. For the purpose of advancing the web through the machine in dependence on variations in leather thicknesses, the rolls and web may be driven at mutually different speeds. <IMAGE>
