- the manufactured Fabric 6 is with a trigger device, not shown deducted.
- the weaving machine additionally contains an edge forming device 7, which is shown schematically in Fig. 1.
- the edge forming device 7 works with two edge threads 8, 9 together, essentially with the respective shed formed 5 matching weaving compartments, in which the registered weft 37 extends so that from the edge threads 8, 9 and the weft threads a selvedge or a waste tape is formed.
- the edge forming device 7 contains a rotatable element in the form of a cylinder 10.
- This cylinder 10 rotates on an axle 12 attached to frame 11.
- This frame 11 is, for example, in the FIG Weft direction adjustable on a weaving machine frame, not shown attached.
- a delivery unit 13 is provided, the edge threads unscrew between the cylinder 10 and the delivery unit 13 should. This turning up takes place in that the delivery unit 13 rotates against the direction in which the cylinder 10 the Edge threads 8, 9 rotates.
- Such a delivery unit 13 and their drives are in U.S. Patents 3,880,199 and 3,998,247 as well as described in CS 172 136.
- a guide groove 14 In the jacket 15 of the cylinder 10 is a guide groove in the form a guide groove 14 is provided which the two edge threads 8, 9 leads so that these are looped around each other.
