Abstract

The treadle device contains, in a housing (1), a number of eccentric discs (11, 11') coupled to a drive, and heald-frame rockers (13) co-operating with these. The eccentric discs (11, 11') are connected fixedly in terms of the rotation to first gearwheels (10) and are mounted on an eccentric shaft (3) which is itself carried by connecting rods (19) mounted on a crankshaft (5). The first gearwheels (9, 10) are in engagement with second gearwheels (8) mounted on a drive shaft (2). For the purpose of co-ordinating the heald-frame rockers (13), the eccentric shaft (3) together with the eccentric discs (11, 11') can be moved away from the heald-frame rockers (13) by means of the crankshaft (5) and the connecting rods (19), the first gearwheels (10) being rolled on the second gearwheels (8) and remaining in engagement with these. Co-ordination can thereby take place without a high additional outlay in terms of construction and with only a small amount of force and the dimensions of the treadle device can be kept small.
