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.
An automatic temple for feeding a web in weaving looms, comprising a stationary hollow bar having a bar bore and having a slot extending outwardly from said bar bore and longitudinally between the ends of said hollow bar, a circularly cylindrical rod of greater diameter than said slot arranged in the bar bore of said hollow bar and being rotatable for winding the web therearound which is fed into the slot around said rod and out said slot, at least the ends of said rod being tubular and having a rod bore, a guide body disposed alongside each end of said rod and being secured to said hollow bar for preventing the rotation thereof, a plurality of circumferentially spaced longitudinal keyways extending through the wall of the tubular part of said rod, a key guided for radial and longitudinal movement in each of said keyways and each having an outer end with a needle point and being radially movable so as to alternately project and withdraw said needle points from the surface of said rod, and means associated with said rod and said guide body to displace said keys upon rotation of said rod.
