PCT No. PCT/CH92/00041 Sec. 371 Date Nov. 5, 1992 Sec. 102(e) Date Nov. 5, 1992 PCT Filed Mar. 2, 1992 PCT Pub. No. WO92/16678 PCT Pub. Date Oct. 1, 1992.A shedding device for a textile machine contains two lifting blades (120) which move to and fro antagonistically, two traction elements (121) which can be engaged and disengaged with the lifting blades (120) and an insertion device (12) which is arranged so that the traction elements adopt a defined position with respect to the pole regions when in the lower shed position. The traction elements (121) have coupling parts (123) with hooks (126) which can be coupled with matching lifting blade parts, and stop parts (54) which co-operate with the stop board (46) for the rest position and with the lower edge of the lifting blade (120) so that they move to and fro interlocked with the traction elements (121) coupled with the blades (120). As a result of this defined position and of the insertion and withdrawal of the traction elements from the lower shed position and the interlocking drive, the power of the electromagnets and of the shedding machine can generally be markedly reduced with a reliable switching function at high frequency up to 2500 min-1.
