Abstract
This invention relates to machines for softening leather, commonly referred to as staking machines, of the type in which leather to be staked is passed between opposed interengageable processing elements the distance between which is periodically increased and decreased by relative movement of the processing elements. The leather is staked by the action of the processing elements as they approach their minimum distance apart. The construction of the machine is such that the processing elements both execute a periodic motion around closed paths e.g. circular paths. The movements of the two processing elements around their closed paths are mechanically synchronized. Thus, the leather is processed and is simultaneously transported by the movement of the processing elements.
Claims2
A machine for the processing of flat, flexible objects, especially for the softening, stretching and glazing of leather;
- said machine comprising two opposed interengageably processing elements between which the objects are through-fed for processing, both the opposed processing elements being mounted for movement around closed circular paths and the processing elements being arranged so that their paths overlap, and at least a pair of eccentric mechanisms for moving each of the processing elements correspondingly around their closed circular paths with a periodic motion whereby the distance apart of the processing elements is periodically increased and decreased so that the object to be processed is processed during the phase of motion in which the paths of the processing elements interengage and overlap and the object is simultaneously transported through the machine by the processing elements, the processing elements having a component of motion in the through-feed direction during the phase of motion in which the paths of the processing elements overlap.
