摘要
An apparatus for producing a continuous succession of pieces or sheets, particularly suitable for infeeding cut pieces of wrapping material to wrapping machines, comprises a track for collating and sending forward the said sheets or cuttings; a plurality of auxiliary tracks leading to the said collation track; means for channelling along the auxiliary tracks, successively, wrapping material from respective reels; and control means for rhythmically cutting such material and for automatically feeding material, end to end, from a fresh reel on exhaustion of an empty reel. The control means comprise sensor means for detecting the end of the material from the empty reel; for cutting from the end portion a piece of material equal in length to or a multiple of the length of the said sheets or cuttings and for thereupon causing material to move forward along another of the said auxiliary tracks so that there is a continuous succession of sheets or cuttings along the above mentioned track where the said sheets or cuttings are collated and sent forward.[US3983774A]
