ABSTRACT:
A drying press for hides, comprising two endless drying felts (1; 4) passed over rolls (2, 3; 5, 6), said felts being pressed against each other at press rolls (2, 5) to form a drying press gap for hides which are passed therethrough, as well as hide stretching means upstream of said gap. A problem to be solved is to provide such hide stretching means that can be used to effectively prevent the folding of the trailing edges of hides to be fed through a drying press. To solve this problem, there are an upper stretcher (8) and a lower stretcher (7) between which a hide (18) is passed while being lifted off a drying felt (1). Stretchers (7 and 8) press a hide therebetween with a suitable sliding fitness, said hide keeping taut and off a felt. Those surfaces of stretchers (7 and 8), which come against a hide, are provided with endless stretching belts (9, 10 and 11, 12) displaceable from the center towards the sides, the travelling speed of said belts being higher than that of drying felts (1, 4) and a hide (18) moving therebetween. The belts (9, 10) of a lower stretcher (7) are mounted on a frame (14) displaceable in the conveying direction of hides.
