METHOD OF FORMING EDGE AND EDGE-FORMING DEVICE OF SHUTTLELESS LOOM FOR MANUFACTURE OF TERRY CLOTH

摘要

Process for the formation of a tucked selvedge in a terry cloth piece, as obtained with the procedure using an articulated reed having two beating-up positions, using a selvedge-forming device which comprises a movable grasping and severing member as well as a second movable member in the form of a takeup hook or the like, characterized by the additional step of keeping said movable members through the entire time during which the weft threads inserted in the shed and beaten up by the reed up to the blind beat position are, in their turn, beaten by the comb against the fell of the fabric being woven. The selvedge-forming device for carrying out the process is then equipped with a weft-slackening humpy blade while its spring biased cam-controlled levers intended to drive said movable members are fitted, at their ends pivoted to the same shaft, with projections or teeth which are adapted to coact with corresponding stop abutments mounted on an arbor which is spring-biased and can be shifted by an electromagnet until bumping into said teeth. A preferred embodiment of a movable grasping and severing member is also described in detail.
