Abstract
An improved container feeding device is for a container cutting machine of the type which can cut any one of numerous sizes of plastic bottles and metal cans. The cutting machine has a cutting section including a plurality of cutting wheels mounted for rotation in opposite directions on a pair of parallel cutting shafts. The improvement includes a pair of parallel feeding shafts each of which are above one of the cutting shafts for rotation in the same direction thereof. Each feeding shaft includes three radially extending, evenly spaced paddles fixedly mounted thereon. The feeding shafts rotate at the same speed and are rotationally aligned to cause each paddle on one feeding shaft to generally lie within a common plane with a corresponding paddle on the other feeding shaft as they pass closely by one another. Each of the paddles has a plurality of gripping teeth on the extended end thereof. Each gripping tooth has a tip which extends between the gripping teeth of the other paddle to produce a radial overlap of each paddle with its corresponding paddle when in the common plane. The extended ends of each paddle and its corresponding paddle cooperate during rotation prior to, throug…
