Definitions

  • the present invention relates to an apparatus for perforating and cutting web material.
  • the apparatus comprises a frame on which is mounted a table top at one end of which can be suspended a material supply roller, while at the other 10 end can be attached a material discharge roller, between which rollers the table top is discontinuous and fitted at that location with one fixed and one adjustable perforation unit, while on the upper shaft of the perforation unit, outwardly of the perforation rollers, there are mounted 15arms the free ends of which are interconnected through a shaft with a freely rotatable hold-down roller mounted thereon, with a circular blade coacting with said hold-down roller.
  • Said circular blade may abut under spring pressure on the end of the hold-down roller.
  • the blade may be disposed on a shaft provided underneath the table top and affixed to the frame, and the table top may be provided at that location with a slot extending parallel to said hold-down roller.
  • the rotating blade can then coact with a counterblade affixed to a disc of the hold-down roller.
  • the blade may be attached at the side facing away from the spring to a disc coacting with the hold-down roller, preferably made of rubber, so that during operation, the web material is taken along without slip.
  • the rotating blade may freely abut on said counterblade under the influence of said spring pressure, which spring pressure is adjustable by means of an adjustable ring slidable along the shaft.
  • web guides may be provided on the table top both upstream and downstream, the web guides provided at the side of the adjustable perforation unit being adjustable as well.
  • a drivable roller may be mounted adjacent the supply roller for taking up residual material cut-off by the blade.
  • Said roller is drivable through e.g. a chain drive by the supply roller driven itself by the web material.
  • the apparatus according to the present invention can also be used for rewinding material to smaller units: to this effect the arms with the hold-down roller attached thereto are mounted for swivelling movement through at least 900.
  • an apparatus for perforating and cutting web material comprises a frame 1 with side cheeks 2 to which is attached a table top 3 having a slot 4 approximately in the middle. Adjacent said slot, the frame has supporting strips 5 rotatably supporting two shafts 6, 7. Shaft 6 supports a fixed perforation roller 8 and an adjustable perforation roller 9 slidable on shaft 6. Perforation rollers 8, 9 are adapted for coaction with the counter-roller 10 mounted on shaft 7 and an adjustable counter-roller, not shown.
  • cheeks 2 are fitted with recesses 11 adapted to receive a shaft 12 of an unwinding roller 13 adapted to receive a core 14 of a roll of material 15 supplied, called in short supply roller.
  • the latter is fitted with a fixed guide disc 16 and an adjustable guide disc 17, having a hub 18 which can be secured to the unwinding roller 13 by means of a socket screw 19.
  • a hold-down roller 23 mounted on shaft 6, outwardly of the perforation - rollers 8, 9 are arms 20, 21, the two free ends of which receive a shaft 22 on which is mounted a hold-down roller 23, consisting of a plurality of separate discs 24 of different widths.
  • a shaft 25 freely rotable in the cheeks 2 of the frame.
  • a rotating blade 26 adapted to coact with a counterblade 27, which is secured by means of a socket screw 56 on the shaft 22 of the hold-down roller 23.
  • the rotating blade 26 is kept in contact with the counterblade 27 by means of a spring 28 and an adjustable ring 29.
  • a disc 30 of rubber or similar material abuts against the rotating blade 26.
  • the table top has a local discontinuity 31 for providing a good coaction between hold-down roller 23, and counterblade 27, respectively, and the rotating blade 26 with the rubber disc 30.
  • the apparatus is provided with a take-up shaft 32, on which shaft are mounted two retaining plates 33, 34, at least the latter of which is adjustable. At the facing sides retaining plates 33, 34, are fitted with a cone 35, 36 for receiving a take-up core 37 shown in a chain-dotted line in Fig. 2.
  • Shaft 32 is received in recesses (not shown) of the side cheeks 2 by means of retaining plates 38, which may be mounted for rotation on the cheeks 2, e.g. by means of pins 39, and be maintained in the retaining position by means of a spring, not shown, enabling an easy change of the tape-up core 37.
  • Take-up shaft 32 has an outward extension.
  • a gear 40 mounted on the extended portion is a gear 40, arranged to cooperate with a gear 41 carried by a shaft 42 mounted on the frame underneath the take-up shaft 32.
  • a hand grip 43 On the square end of the shaft 42 is mounted a hand grip 43 for rotating the take-up shaft 32.
  • this is fitted, along a major portion of its length, with fixed guide strips 54 on one side and with adjustable guide strips 55 on the other side.
  • the shaft 22 is extended outwardly and a plurality of discs 44 of different widths are disposed on said extended portion.
  • the diameters of said discs correspond with those of the discs 24.
  • On the frame are also mounted a pair of upwardly directed supports 45, the free ends of which have a recess 46 for receiving a shaft 47 on which is mounted a residue take-up core 48.
  • the drive of the residue take-up core takes place via a rope pulley 50 mounted on a projecting portion of shaft 47.
  • a rope 51 running over the rope pulley 50 further engages a rope pulley 52 mounted on the unwinding shaft 12.
  • Rope pulley 51 is kept under tension by means of a tensioning roller 53, which abuts against the rope pulley under spring tension in a manner well known, and hence not further described herein.
  • the shaft 12 is received in the respective recesses of the frame by means of easily releasing retaining discs 54.
  • the hold-down roller 23 with the arms 21 can be swivelled upwardly into the position shown in chain-dotted lines. In that position, a foil can be passed from a supply roller to a take-up core: in this manner it is possible with the apparatus to also distribute the foil of the supply roller in a simple manner over a plurality of take-up cores to be mounted successively on the take-up shaft.
