Definitions

  • This invention has reference to paper and the like web severing mechanisms of the kind, sometimes referred to as Bursters, in which a continuous web of paper with cross perforations is fed between two pairs of rollers of which the outfeed pair of rollers have a larger feeding speed than that of the infeed pair of rollers.
  • the rollers are so disposed that the paper web is severed across the lines of cross perforations with a bursting action.
  • a paper or like web severing mechanism comprises a pair of infeed rollers and a pair of outfeed rollers, drive means for driving the outfeed rollers at a higher speed than the infeed rollers and a pair of spaced arcuate guides between which the paper is fed between the rollers.
  • One of the features of novelty of the invention is the provision in a vertical arcuate burster as described, of receiving and delivering means both disposed upon the same side of the machine and the sheet delivery receptacle positioned above the support for the web to be fed through the machine.
  • This provision has at least two advantages, one in permitting the machine to be attended by a single operator, and another the ability to position the machines in back-to-back relationship or to locate a machine with its back toward the wall of the room, all efiecting economies in space and labor.
  • FIG. 1 is a sectional side view of the mechanism
  • FIG. 2 is a plan view with the cover removed.
  • the paper severing mechanism comprises an infeed tray 1 on which for example, a pack of a continuous paper stationary web 2 to be severed is stacked.
  • a pair of parallel spaced infeed guides 3 are located above the stacking tray.
  • a guide roller 4 is mounted on the infeed end of these guides 3 and a curved bracket 5 is located around the centre part of the roller 4 to divert the web into the guides 3.
  • Sleeves 6 are secured on the roller 4 and are adjusted so as to be spaced apart a distance slightly greater than the width of the stationary web to severed.
  • the parallel guides consist of a lower flat plate and a fiat plate resting on the lower flat plate.
  • the upper flat plate has flanges at its sides deeper than the thickness of the stationary web being severed so that the plates are spaced apart a distance slightly greater than the thickness of the web.
  • These guides 3 are mounted to guide the Web in a horizontal plane and in a straight line path into a plurality of pairs of infeed guides 7 which direct the web into a pair of spaced guides 8 arranged in an arc of a circle. This arc extends for approximately 90 and the guides 8 are so arranged that the web is fed into the guides in a vertical direction and out of the guides in a horizontal direction.
  • The has a radius of about eight inches. As shown, nine pairs of guides are spaced across the paper severing mechanism,
  • each guide has a width of about three quarters of an inch and each pair of guides are disposed apart by a distance of about one eighth of an inch throughout their arcuate lengths.
  • a pair of outfeed rollers 9 and 9 are mounted in a fixed support at the outfeed end of the arcuate guides 3 one vertically above the other.
  • These rollers 9 and 9' are each castellated, that is to say they have cylindrical parts of a large diameter separated by cylindrical parts of a smaller diameter.
  • the large diameter parts of one roller are opposite the large diameter parts of the other roller.
  • the large and small diameter parts each have a length of about one inch.
  • the upper roller 9 is of steel and the lower roller 9' is of rubber.
  • the upper roller is mounted in a bearing'with a cooperating screw indicated diagrammatically at 9a so arranged that the upper 4 roller can be adjusted to be in frictional driving engagement with the lower roller.
  • a stripper guide 10 is located adjacent the outfeed side of the lower outfeed roller 9'.
  • the outfeed rollers 9 and 9 and guides 8 are supported between side plates 11. A pair of infeed rollers w cross bar.
  • the infeed roller 12' and outfeed roller 9' are driven by an electric drive motor 20 with a connecting drive 21 to a drive sprocket 22 on the shaft 14 at the centre of the circle on which the arcuate guides lie.
  • An endless belt connection 23 is made to the inner feed roller 12' of the infeed guides and this inner feed roller 12' drives the outer feed roller '12 by friction.
  • a drive belt connection 24 is also made from the drive sprocket 22 to the inner roller 9' of the outfeed roller.
  • the outer roller is likewise driven by friction with the inner roller.
  • the drive is connected so that the outfeed rollers are driven faster than the infeed rollers.
  • the drive shaft 24a to the drive motor 20 is extended outside the side plates 11 and a feed wheel 25 is afiixed to the end of this shaft so that the rollers can be driven manually.
  • a feed tray 26 is located at the outfeed side of the outfeed so that form lengths detached from the web 2 fall on to the tray in stacks.
  • a guide 27 is adjustably mounted on the tray 26 so that the tray can accommodate different sizes of form lengths.
  • Three stacking rods 23 are located on shaft 29 to assist in stacking the form lengths.
  • a pivoted cover 30 is arranged over the guides to prevent the mechanism operator from becoming entangled with the rollers and other moving parts.
  • the continuous web in pack form is loaded onto the infeed tray 1 and threaded between the guides 3 and the guides 7 to the arcuated guides 8 and the infeed rollers 12.
  • the leading edge of the web is then fed between the infeed rollers and arcuate guides 8 toward the outfeed rollers by rotation of the feed wheel 25.
  • the motor is then started and the web is fed by the infeed roller until the leading'edge of the Web reaches the outfeed rollers.
  • the outfeed rollers then grip the leading edge. Because the outfeed rollers are feeding at a rate faster than the infeed rollers 21 snatch action is given to the web which causes the leading form length to be detached from the remainder of the web across the tear off perforation.
  • the positioning of the arcuate guides facilitate the initiating of the bursting action which is continued across the cross perforation. It is required that-the position of the infeed rollers shall be so arranged that a tear oif perforation shall be located between the two rollers when the leading edge of the leading form. length engages between the outfeed rollers. It is of course, also required that a single tear oil perforation shall be located between these two rollers at this time.
  • the position of the cross bar 15 is adjusted by moving the two catch oars-together to move the outer ends of these catch bars 16 from the appropriate pair of holes 13 in the side plates 1.
  • the cross bar 15 is then moved to the position required by the length of theform to be severed, that is that the distance part of the two rollers shall be slightly in excess (measured around the arcuate path of the guides) of the length of the form length to be severed and: the catch bars 16 are located in another pair of holes 18.;
  • the stationary web of the different form length can then It has also been found desirable to include a counterbalancing means, indicated diagrammatically at 32 which acts to counterbalance the infeed rollers 12 to permit them to be easily adjusted. Thus by altering the position of these rollers different form lengths of the stationary web being bursted can be easily accommodated.
  • This counterbalancing means 32 may comprise a torsion spring.
  • said means including a web and sheet I means for adjusting the position of at least one of said be loaded into the severing mechanism as hereinbefore- 1 pairs of rollers along said arcuate guide to space the infeed and outfeed rollers at appropriate distances apart for the selected sheet length; means for driving said outfeed rollers at a greater speed than said infeed rollers, a sheet web support adjacent the receiving point and a sheet pile support adjacent the delivery point and above the web support on the same side of the machine.
