Abstract
A winder for making coreless rolls of pliable sheet material, such as plastic, cloth or paper, includes a cut-off section for severing a continuous strip of feed material to the desired length and a conveyor system downstream thereof. A portion of the conveyor is pivotable between a first and second position to feed spaced-apart winding rod assemblies. The rod assemblies each include a pair of elongate, spaced-apart rods and a mechanism for rotating the pair of rods to wrap the feed material into a coreless roll. The rod assemblies also include a system for collapsing one of the two rods toward the other when the winding of the roll is completed and it is desired to dispense the coreless roll. A finger mechanism is also provided for properly orienting the pair of rods to receive the leading end of the pliable material. By employing multiple winding assemblies and the pivotable conveyor system, the speed of the winder can be substantially increased. The present invention is especially suitable for the winding of rolls of dropcloth or other cover-sheet materials.
