Abstract

A multiplicity of teeth are mounted to a beam in a comb structure, with the space between the teeth defining slots. The edges of the slots are lined with upstanding flanges which are sharpened to form cutting edges. The comb structure is arranged to be substantially parallel to an array of bag breaking bars. The bars interdigitate with the teeth and thus pass through the narrow openings between the teeth where the knife edges scrape the bars, thereby cutting free any material adhering to or impaled upon the bag breaking bars. Alternatively, an apparatus for cleaning a bag breaker has a pivotally mounted are having a fork which is aligned to receive a bar between the tines of the fork. The fork engages the base of the bar and then proceeds to slide up the bar as the forward motion of the bar causes the arm to pivot. In this way, material impaled upon a bar is slid or scraped upwardly towards the top of the bar. When the fork reaches the top of the bar and has thus removed any material impaled upon the bar, it pivots in response to an attached spring back to its initial position wherein it engages the next bar in sequence.
