Definitions

  • the invention relates to the production of. rectangular sheets of flat goods, in particular of textile floor coverings, e.g. from carpet slabs to form a floor covering or from carpet sample pieces to show off.
  • Carpet sample pieces or carpet slabs must be cut to size and have edges that run at right angles to one another, so that on the one hand they fit into a size-fixed sample collection and on the other hand they fit together seamlessly during the mosaic-like assembly.
  • the cut edge of carpet panels must also be clean and regular with regard to the pile material.
  • Carpet sample pieces also require post-processing, which consists in preparing the panels at the cut edges by chamfering the pile from the pile with an edge cutter in order to prevent fraying.
  • the plates must be cleaned of dust and fiber snippets that are produced during cutting and preparation. The finished plates are then labeled and kept in stacks for further use.
  • the invention now relates to a method for the mechanical production of rectangular plates from flat goods, in particular from textile floor coverings, which enables plates to be cut to size and cleanly * in continuous work processes.

  • the punching knife 38 is clamped with screws 40 on the yoke 41 of the eccentric press, which is moved back and forth, and is supported on the rear by adjusting screws 42.
  • a motor 43 is used to drive the eccentric press, which drives the shaft 45 with the two eccentric disks 46 via a clutch 44, which in turn are in operative connection with connecting rods 47 with the push rods 48 on the yoke 41.
  • spring means 49 are coaxial to the push rods 48, e.g.
  • a number of disk springs each are provided, which catch the moving mass in the area of the lower dead center during the cutting process and at the same time cancel any play in the drive parts in order to ensure that the cutting edge 50 of the punching knife 38 touches the hard one until it is completely touched Underlay, but a rivet effect on the knife edge is prevented.
  • a bar made of hardened steel is preferably used as the hard base. 6, the lower leading edge for the goods is indicated at 71.
  • a hole punching device 51 with one or more interchangeable punches 52 is also mounted on the yoke 41. If necessary, it is actuated simultaneously with the punching knife 38 in order to provide the plates with a punched hole.

  • Each belt conveyor has two conveyor belts 56, 57 and 58, 59 receiving the goods 55 between them, of which one conveyor belt 56 or 58 along a stationary support 60 or 61 and the other conveyor belt 57 or 59 along a conveyor belt.
  • the supports 60 and 62 of the feeding belt conveyor 53 are shaped in such a way that the relevant conveyor belts 56 and 57 run in a wedge shape with respect to one another on the inlet and outlet sides, so that entrainment elements provided on the conveyor belts, for example transverse ribs, are approximately perpendicular towards the transported goods and move away from them.
  • the slip-free supply of the goods can also be supported by the fact that certain mandrels are provided on the conveyor belt 56 of the feeding belt conveyor 53 to penetrate the goods.
  • the carriers 64 and 65 of the two conveyor belts 57 and 59 which can be displaced transversely to the feed direction and are connected to one another in terms of drive, are preferably guided loosely and connected to one another by a link 66, whereby the link to the
  • the conveyor belts 56, 57 of the feeding belt conveyor 53 are driven in a slip-free manner via chains or chain belts 67, 68 by a motor 69, and these conveyor belts themselves are also designed in the manner of chain belts, so that the feed path of the conveyor belts 56, 57 is exactly proportional the rotor rotation angle of the motor 69.
  • a generator 70 as a clock generator, which, owing to the non-slip relationship with the belt conveyor 53, generates a clock pulse sequence with a pulse frequency proportional to the feed speed of the conveyor belts 56, 57 and thus to the goods 55, either directly or via a pulse shaper.
  • a control pulse for actuating the clutch 44 of the cross cutter 26 is generated after counting a selectable number of clock pulses.
  • the preset number of the counted clock pulses is therefore a measure of the feed path covered and thus of the length of the strip piece cut off in each case.
  • Each edge milling cutter has a cutter head 73, which is driven by a motor 72 and has helical knife edges 74 which contact the cutting edge of an adjustable feed knife 75 without contact work together.
  • a prerequisite for such a low-wear mode of operation is an unbalanced running of the rotating one.
  • the knife combination can be ground in in the reverse direction of the knife head 73.

This measure is important in view of the required high effectiveness of the brushing machine, which is aimed at the one-time passage of the plates.
  • the brush rollers 86, 87 are arranged in a housing 89 which closely surrounds them and is connected to a suction channel 91 on the side facing away from the working plane 88 by a slot-shaped connecting channel 90 between the brush rollers.

Abstract

Le procede et le dispositif pour sa mise en oeuvre permettent la fabrication de plaques et echantillons de moquettes et tapis a dimensions et angles exacts a partir de pans de tapis. Dans une premiere etape on aligne d'abord la matiere selon un bord longitudinal sur une table de dressage (3) a rouleaux obliques (4) et, ensuite, on la decoupe selon sa longueur en plusieurs bandes d'egales largeurs au moyen de plusieurs couteaux circulaires rotatifs disposes dans une enceinte (7). Dans une seconde etape, les bandes sont amenees de chant et sans glissement vers un dispositif de coupe transversale (26) ou elles sont coupees en plaques par un couteau travaillant sur une surface dure. L'operation de decoupage est commandee par une commande a impulsion couplee avec le dispositif d'avance en fonction de l'avance. Des dispositifs (32 a 36) d'appretage, de nettoyage, d'etiquetage et d'empilage des plaques ou d'echantillons de moquettes sont disposes a la suite du dispositif de coupe transversale. La matiere avance de facon continue dans les deux etapes.
