Abstract
Process and apparatus for folding and interleaving continuously moving strips of paper and cutting the interleaved strips into packets of interleaved paper sheets. A supply roll of paper strip is provided for each sheet of paper in a packet, and the strips are simultaneously drawn from the supply rolls and through a series of formers and interleavers to provide a continuously moving strand of interleaved paper strips. The packets are cut from the continuously advancing strand by severing means which moves along with the strand during cutting.
Claims8
Apparatus for folding and interleaving continously moving strips of paper and cutting the interleaved strips into packets of interleaved paper sheets comprising
- a plurality of rotatably mounted supply rolls of paper strip for continuously supplying strips of paper,
- a series of formers and interleavers positioned sequentially outwardly from the supply rolls to fold and interleave the strips of paper,
- drive means for continuously drawing strips of paper from the supply rolls and through the formers and interleavers to to form a strand of interleaved paper strips,
- a knife for cutting the strand of interleaved paper strips into interleaved packets of paper sheets of predetermined length,
- the knife being mounted on a movable knife plate carried by a platform,
- means to reciprocably move the platform in a direction parallel to the direction of travel of the strand of interleaved paper strips a distance equal to the determined length of the packets,
- means carried by the platform to reciprocably move the knife plate in a direction normal to the reciprocal movement of the platform, the knife plate advancing and the knife severing a packet from the strand during movement of the platform in the same direction and at the same speed as the moving strand, and
- a pusher plate carried by and movable with the knife plate to displace a severed pocket laterally with respect to the direction of travel of the strand.
