ABSTRACT:
An automatic temple for feeding a web in weaving looms, includes a hollow tubular bar of a length comparable to the entire weaving width and which has a bore with a slot in the wall thereof extending outwardly from the bore and longitudinally between the ends of the hollow tubular bar. A circularly cylindrical rod is of a greater diameter than the slot and is disposed within the bore of the hollow tubular bar and it is rotatable therein for winding the web therearound which is fed into the slot around the rod and out the slot at a spaced location from its entrance. The cylindrical rod has hollow tubular end portions and it is also movable during winding against the slot. The cylindrical rod has a plurality of circumferentially spaced longitudinally extending keyways defined through its hollow end portions and a plurality of keys are guided for radial movement in the keyways and they have outer ends with needle points. The keys are displaceable radially so as to alternately project and withdraw the needle points from the surface of the cylindrical body. Drive means are connected between the cylindrical rod and the keys to cause the keys to cyclically extend and withdraw the needle points during operation.
