  • strand choppingapparatus comprising a backingroll and cutting means associated with the backingroll so that a strand introduced between the backing roll and the cutting means is cut into predetermined lengths characterised by the provision of a frusto-co'nical portion on the backing roll and a slotted guarddevice shaped to prevent the hand of an'operator being caught between'the'roll and the cutting means and to guide a strand through the slot to contact the conical part of the backing roll.
  • the guard .deviceipreferablyv includes a box like guard provided w-ith-an opening through which the frusto-conical portion of the backing .roll projects.
  • the rolls 2, 3, are set to run at say 200 to 300 feet per minute and the strand 1 is hand-pulled vertically downwards in the direction of the arrow A in FIG. 1 so that it extends behind a part of an inturned lip 7 on the guard 4 see FIG. 2.
  • the strand end below the guard 4 is then moved smoothly to the'right in FIG.
  • guard 4 is completely circular and the mounting means (not shown) ispreferably positioned at the top right hand quarter where it does not 'interfere'with the strand or strands.
  • the guard 8 is essentially a box with a hole cutin it toallow the end core of the roll 2 to project and also providing a slot or aperture6 so positioned that a running strand can enter the nip laterally and theslot-is extended horizontally to guard device also preferably includes a substantially circular guardplate arranged around the frusto-conical portion of the backing: roll and provided with an inturned lip.

  • FIG. 3 is a partial view showing how a' cutter roll,-usu-' ally called the chopperbody, co-operates with abacking roll.
  • FIG. 1 a strandl is seen descending from a bushing indicated generally at 10, abacking roll is shown at 2 and a cutter roll at 3 with blades 9,a circular or similar guard plate 4 being provided around the end of the backing roll which projects through an opening in the wall of a second or box-like guard 8.
  • the backing roll 2 has a frustoconical portion 5 at the projecting end and that the guards 4 and- 8 areshaped to provide an aperture or slot allow the strand to be pulled into the'nip.
  • guards may be regarded asforming a single guard assembly to offer a safeguard to'an operator and with a slot or aperture to allow the strands to pass into the apparatus.
  • the present invention is also of use for cutting strands from rovings or cake-creels.
  • the pres- Y 'ent invention would be operably arranged with the axes v of the cutter roll 3'and backing roll 2 parallel and in a common horizontal plane; Effectively this amounts to rotation of FIG. l'of the accompanyingdrawings through
  • the cutter and backing rolls may be orientated in any manner suitable for carrying out chopping.
  • starting speeds of 200 300 feet/minute are mentioned in the general description of the cutter and its operation, greater starting speeds, say up to 700 feet/minute, may be used if the material being chopped will withstand such starting speeds.
  • LA strand chopping apparatus comprising a backing roll and a cutter roll with projecting blades associated with the backing roll so that strands introduced between the backing roll and the cutter roll are into predetermined lengths characterized in this, that the backing roll is provided with a frusto-conical end portion positioned to project through an aperture in a guard box forming part of a guard assembly which also includes a substantially circular guard plate, a slot being provided between the guard plate and the guard box through which in operation strands are moved sideways into contact with the frusto-conical end portion of the backing roll which guides the strands into a position in which they are nipped between a cutting blade and the is provided with an inturned lip.
