Abstract
An apparatus for perforating and cutting web material, comprising a frame (1) on which is mounted a table top (3) which is discontinuous (11) and fitted at that location with one fixed (8) and one adjustable perforation unit (9). On the upper shaft of the perforation unit, outwardly of the perforation rollers (8, 9) there are provided arms (20, 21) the free ends of which are interconnected by means of a shaft (22) with a freely rotatable hold-down roller (23) mounted thereon, with a circular blade coacting (26) with said hold-down roller (23).
Description
- The present invention relates to an apparatus for perforating and cutting web material.
- It is an object of the present invention to provide a simple apparatus of the above type by means 5of which composite, web material can be rapidly cut to the desired width and be provided with a perforation.
- To this effect 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. By driving the material discharge roller by means of a transmission, web material can be cut in a simple 20manner and subsequently be perforated.
- Said circular blade may abut under spring pressure on the end of the hold-down roller. By dividing the hold-down roller longitudinally into a plurality of portions or discs of differing lengths, the blade can be set in different positions in a simple manner.
- In a further embodiment of the present invention, 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. In order to achieve a good support of the web material at the location of the slot, 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. There is thus obtained a very simple apparatus.
- Furthermore, 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.
- In order to prevent a random discharge of the cut-off residual material, 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.
- One embodiment of the apparatus according to the present invention will now be described by way of example, with reference to the accompanying drawings, in which:
- Fig. 1 is a diagrammatic side view of an apparatus for perforating and cutting material;
- Fig. 2 is a top view of the apparatus shown in Fig. 1; and
- Fig. 3 shows an enlarged detail of the apparatus shown in Figs. 1 and 2.
- As shown in the drawings, an apparatus for perforating and cutting web material comprises a frame 1 with
side cheeks 2 to which is attached atable top 3 having a slot 4 approximately in the middle. Adjacent said slot, the frame has supportingstrips 5 rotatably supporting two shafts 6, 7. Shaft 6 supports a fixedperforation 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. - At the left,
cheeks 2 are fitted with recesses 11 adapted to receive ashaft 12 of anunwinding roller 13 adapted to receive acore 14 of a roll ofmaterial 15 supplied, called in short supply roller. In order to limit the movement of the supply roller or the core thereof on theunwinding roller 13, the latter is fitted with afixed guide disc 16 and anadjustable guide disc 17, having ahub 18 which can be secured to theunwinding roller 13 by means of asocket screw 19. - Mounted on shaft 6, outwardly of the perforation -
rollers 8, 9 arearms shaft 22 on which is mounted a hold-down roller 23, consisting of a plurality ofseparate discs 24 of different widths. As shown in more detail in Fig. 3, there is mounted adjacent the hold-down roller 23 underneath the table top 3 ashaft 25 freely rotable in thecheeks 2 of the frame. On said shaft there is provided a rotatingblade 26 adapted to coact with acounterblade 27, which is secured by means of asocket screw 56 on theshaft 22 of the hold-down roller 23. The rotatingblade 26 is kept in contact with thecounterblade 27 by means of aspring 28 and anadjustable ring 29. As shown in Fig. 3, adisc 30 of rubber or similar material abuts against the rotatingblade 26. Naturally, the table top has alocal discontinuity 31 for providing a good coaction between hold-down roller 23, andcounterblade 27, respectively, and the rotatingblade 26 with therubber disc 30. - At the end opposite the unwinding roller, the apparatus is provided with a take-
up shaft 32, on which shaft are mounted tworetaining plates sides retaining plates cone core 37 shown in a chain-dotted line in Fig. 2.Shaft 32 is received in recesses (not shown) of theside cheeks 2 by means of retainingplates 38, which may be mounted for rotation on thecheeks 2, e.g. by means ofpins 39, and be maintained in the retaining position by means of a spring, not shown, enabling an easy change of the tape-upcore 37. Take-upshaft 32 has an outward extension. Mounted on the extended portion is agear 40, arranged to cooperate with agear 41 carried by ashaft 42 mounted on the frame underneath the take-up shaft 32. On the square end of theshaft 42 is mounted ahand grip 43 for rotating the take-up shaft 32. - The operation of the apparatus will be clear after the above description: After placing
supply roller 15 on theunwinding core 13, the operator will pull off the web from it and pass the web manually underneath the rotating blade, between the perforation rollers and subsequently onto the take-up core. Thereafter the drive can be taken over by thehand grip 43. - In order to ensure a good guidance of the foil during its movement over the
table top 3, this is fitted, along a major portion of its length, withfixed guide strips 54 on one side and withadjustable guide strips 55 on the other side. - To avoid problems with respect to the strip discharged, the
shaft 22 is extended outwardly and a plurality ofdiscs 44 of different widths are disposed on said extended portion. The diameters of said discs correspond with those of thediscs 24. On the frame are also mounted a pair of upwardly directedsupports 45, the free ends of which have arecess 46 for receiving ashaft 47 on which is mounted a residue take-upcore 48. For confining the residual material, there are provided onshaft 47 twoguide discs 49, at least one of which is adjustable. - The drive of the residue take-up core takes place via a
rope pulley 50 mounted on a projecting portion ofshaft 47. Arope 51 running over therope pulley 50 further engages arope pulley 52 mounted on theunwinding shaft 12.Rope pulley 51 is kept under tension by means of atensioning roller 53, which abuts against the rope pulley under spring tension in a manner well known, and hence not further described herein. For the purpose of a ready release of the rope pulley, theshaft 12 is received in the respective recesses of the frame by means of easily releasing retainingdiscs 54. - As best shown in Fig. 1, the hold-
down roller 23 with thearms 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. - It will be clear that a great many modifications are possible within the scope of the present invention.
