Loom bobbin stripper

Abstract

A rotating-reel type loom bobbin stripper provides air jets to entrain the waste end of yarn from a bobbin and deliver it to the stripping reels without impinging the jet directly on the yarn bunch. Bow springs automatically apply proper yet readily-releasable tension to the belts feeding the bobbins serially over the reels. A hold-down bar above the row of bobbins being stripped may be lifted readily to clear a jam. Downwardly inclined guide rails deliver bobbins to the feeding belts at an angle causing the bobbins to support themselves by their own heads during delivery and allowing loose waste to be blown down between rails and bobbins by an air jet. The inside walls of the incline rails are relieved to allow any 'piece bobbin' which slips into normal position between the rails to travel on freely. A monitoring arm over the incline rails holds back normal 'high bobbins' until they are able to fall to normal position hanging between the rails; and it also acts to lever high-riding 'piece bobbins' out of the guide rails and over the side. A pair of upwardly inclined feeder belts for receiving, sorting and feeding bobbins upwardly is automatically properly tensioned by a spring, and tapered pulleys act to support most of the weight of the belts while guides at the lower belt edges support a small part of the belt weight and maintain constant spacing between the belts. A bobbin-deflecting and detaining arm near the top of the inclined rails is equipped with a hanging hinged end to detain at least one bobbin there as a buffer for succeeding bobbins. A blower creates air flow past the stripping reels, through a filter, and delivers filtered air to the gears driving the reels. A conveyor carries away unstripped bobbins plus loose waste on a self-tensioned belt trained over pulleys protected from clogging with waste.
