ABSTRACT:
Apparatus for pulling a line, particularly a line having a low coefficient of friction such as an endless line oil mop. A pair of endless belts are positioned so that their facing portions define a converging space. A plurality of slats are positioned on each endless belt oriented transverse the longitudinal axis thereof. On each endless belts the slats are alternately of a first hardness and a second, lesser hardness, with each hard slat on each belt being opposite a softer slat on the other belt. The softer slats deform somewhat, and so the line is crimped between the alternating hard and soft slats. Idler rollers deform the endless belts and the slats into the converging space to massage the line as it passes therethrough, and this massaging is enhanced by guide rails which cooperate with the idler rollers. An auxiliary endless belt unit can be provided adjacent the converging space outlet and having its facing portions traveling away from that outlet at a higher linear velocity than that of facing portions of the main unit. The resulting slippage between the auxiliary unit and the line reduces entanglement of the line and refluffs the fibers on an endless line oil mop. A three-tiered unit utilizing three endless belts to provide two converging areas can be constructed to give increased gripping of a line and increased cleaning of an oil mop.
