Definitions

  • the invention relates to a cutting device for cutting to length soft strip material, such as fabric or the like.
  • a conveyor belt supplying the material of a cutting station having a fixed bottom knife and a movable top knife
  • the bottom knife of the cutting station arranged above the conveyor belt forms a run-up surface sloping against the conveyor belt and a cutting edge lying parallel to the conveyor plane and interacting with the upper knife.
  • the invention is therefore based on the object of eliminating these deficiencies and of creating a cutting device of the type described at the outset which ensures continuous cutting of soft strip material in a simple, functionally reliable and rational manner and thereby enables the proper further transport of the cut pieces.
  • the invention solves this problem in that, as is known per se, the conveyor belt is divided in at least two widths and the lower knife carries projecting guide tongues from the run-up surface into the gap area between the conveyor belt parts.
  • These guide tongues bring about a functionally reliable sliding of the strip material from the conveyor belt onto the run-up surface, since they grip under and lift off the material delivered by the conveyor belt.
  • the strip material to be cut therefore always comes to the cutting edge of the lower knife without any delay and can be cut to pieces of a certain size with the upper knife, which pieces are lined up on the conveyor belt after the cutting station.
  • a strip material can also be cut in a simple manner, which is composed of a continuous web, for example a nonwoven web, and thus glued, lined up pieces of fabric. Because the distances between the individual pieces of fabric are only covered by the thin strip of nonwoven, the light barrier can precisely detect the beginning and end of these pieces of material and control the top knife so that the nonwoven strip is cut to length exactly between the pieces of material without damaging them.
  • the cutting device for cutting strip material which is denoted as a whole by 1, consists of a conveyor belt 2, which is divided in width into several belt parts 2 ', and a cutting device station 3 with a fixed plate-shaped lower knife 4 and a liftable and lowerable upper knife 5.
  • the lower knife 4 is arranged above the conveyor belt 2 and forms a run-up surface 6 leading from the conveying plane of the conveyor belt, which in a cutting table 7 with a cutting edge 8 parallel to the conveying plane transforms. From the run-up surface 6, guide tongues 9 protrude between the conveyor belt parts 2 ′, which grip under the material being conveyed and transfer them to the run-up surface 6.
  • Air nozzles 10 below the conveyor belt 2 can also produce an air cushion in this transition region between the conveyor belt 2 and the ramp surface 6, which allows the strip material to be removed from the conveyor belt 2 in a completely trouble-free manner.
  • a vertical light barrier 11 is provided, which runs between two conveyor belt parts 2 'and a corresponding control bore 12 of the lower knife 4.
  • the cutting device 1 is arranged downstream of a fixing press 15, which is only indicated, which glues pieces of fabric 16 strung together in a continuous workflow with a continuous nonwoven web 17 and transfers this strip material to the conveyor belt 2.
  • the conveyor belt 2 brings this material into the area of the cutting with the participation of the transport rollers 13 station 3, where it is lifted due to the guide tongues 9 and the air nozzles 10 and pushed along the ramp surface 6 of the lower knife 4 to the cutting table 7. It travels back over the cutting edge 8 back to the conveyor belt 2, the upper knife 5 cutting through the nonwoven web 17 as soon as the light barrier 11, which the nonwoven web 17 but cannot penetrate the pieces of fabric 16, signals that the cutting edge 8 lies between two pieces of fabric 16.
  • the resulting individual pieces which now each consist of a piece of fabric 16 and a nonwoven piece 17 associated therewith, remain properly lined up and are fed with the conveyor belt 2 for further processing, for example for the production of bundles for garments.
