Abstract
The invention relates to a device for fleshing, stretching and drying leather or similar flat materials such as skins and furs. The device consists of movable lamellae which can be extended from the center outwards and which under vacuum and the cooperation of a pressing device provides a smooth, gliding heatable contact surface on which the stretched and fixed piece of leather is simultaneously dried thereby minimizing any frictional forces encountered when stretching leather in a vacuum. Moisture is evacuated through channels, raised areas, perforations in one of the lamellae thereby improving the stretching effect and uniformity of the stretched leather across its entire surface without wrinkling.
Claims11
A device for the dewatering, stretching and drying of leather, similar flat materials and pieces thereof, having an interstice, sealed by a gasket and connected to a vacuum source for the leather piece and consisting of a support surface, above which lamellae are mounted with a drive mechanism to deploy said lamella outwards from the centre, and a contact pressure device consisting of a second lamella system fitted to a rigid, inextensible plate, connected to a stretching mechanism and mounted as a mirror image of the lower lamella system, whereby the lamellae can be deployed outwards by a circular movement around a fixed pin.
