ABSTRACT:
A sheet (4) to be stretched is gripped in gripping heads (1, 2) interconnected by pressure members 3, the gripping heads being moved apart by hydraulic cylinder units. Owing to the different lengths of sheet to be stretched, one of the gripping heads--the counter gripping head (2)--is movable and may be locked to the pressure members (3) in different positions. In order to facilitate better adjustment between the pressure members and the gripping head (2) opposite sides of the pressure members (3) are provided with teeth (12, 13) removably engageable by toothed locking members (14, 15). Engagement is carried out by hydraulic cylinders operating axially-displaceable wedges (16, 17) connected to the locking members (14, 15).
