Definitions

  • This invention pertains to improvements in bag tubing machines for making multiwall paper tubes, in bag lengths, for the production of multiwall paper bags therefrom.
  • the invention pertains to machines of this type especially adapted for making multiwall tubes for so-,called stepped-end bags, to be subsequently formed into the nished bags on a bottoming machine.
  • the bag end edges will have three steps formed of three of the plies, two of which are duplicated by the remaining two plies so thattwo of the plies do not vpresent individual stepped ends.
  • the machine here disclosed may be set up and adjusted for making other forms of steppedend bags, and in fact the machine is also adapted for making multiwall bag tubes of various types which do not have stepped ends.
  • the webs in separated condition may at rst be individually perforated part way across the web only, viz. at the parts which are to form the middlesteppedend Y portions of the tube, whereas the portions which are Yto form the sides of the tube (that is.
  • theve'nd flap portions at the bottom of the iinished bag) ⁇ may be left unperforated and not cutl until after the tube is formed in the tuber, .thus leaving the webs in strong condition, capable of being pulled rapidly through the machine without danger of separation at the perforations, even though the per-forations may have been so effectivelymade as to weaken or sever the greater part of lthe vi'ibre along the middle portion of the endfedge of the bag. Then, just before the tubeit is only necessary to pull the tube lengths apart along relatively weak lines of perforation across the middleportion of the bag ends. But despite the general advantages of making stepped-end bags according to the above-mentioned Hoppe patent, the construction oi a commercially practical machine lor automatically carrying out this method involves additional serious diliculties,
  • the machine is so' constructed that various registry adjustments4 for the necessary perforating, slittingand cutting operations on'the paper webs, and for the degree or extent of stepping or overlapping 1' ofthe successive plies at the bag ends, can be made from a single control position, and while the machine'is either stationary or running, by s iinple manipulation 'of hand wheels or clutch controls. Also, registry adjustmentscan be made,

  • rlhe webs are fed thence through a tube-forming unit which forms the webs into a continuous tube, each ply of which is glued to itself along the longitudinal seams formed by the stepped, lateral edges.
  • the continuous multiwall tube may pass through a slitter which appropriately slits the tube longitudinally at bag lengths adjacent the opposite edges thereof, and in the regions of the transverse perforations therein, the tube passing thence through a cutter which cuts the tube into bag lengths adjacent its lateral edges, and separates the successive plies thereof; along thelines of perforations therein, thereby to produce multi- Ywall tubes of bag length, the successive plies of which are glued to each other by the transverse glue lines, -the-said tubes having ends appropriately stepped and slit for subsequent forming into of Fig. f1; while Fig. v1b is a AcQntinll,@tion o f la ⁇ astaken along the linee-b or Fig. la.
