ABSTRACT:
A looper used in the manufacture of asphaltic roofing felt comprising a driven endless belt of spaced tubes adapted to carry loops of felt between adjacent tubes, a track inclined toward said loops, a trolley having fingers adapted to contact the foremost loop in the looper, rollably mounted on the track wherein the improvement comprises a chain driven at the same rate and in the same direction as said endless belt and means on said trolley to interlock with said chain actuated when said fingers have contacted the foremost loop whereby the trolley travels with the foremost loop and the fingers maintain a constant pressure or contact on the foremost loop, until the loop is pulled out of the reach of the fingers, whereby the fingers drop and deactuate the interlock means, allowing the trolley to roll by force of gravity until the fingers again contact the foremost loop and the operation is repeated.
