  • Patent number: 4683658
    Abstract: A manually controllable machine for cutting out or notching fabric has a supporting foot (2) for supporting the machine on a cutting table (). The foot (2) has a flat face (15) on which the machine rests. To reduce the effort required to displace the machine, at least one opening (25) of at least one channel (16 to 21) is provided in the face (15), the channel (16 to 21) being connected to a source of compressed air.

  • Patent number: 4572495
    Abstract: The apparatus comprises a laying carriage which travels over a laying surface to deposit web material on the surface. The web material falls as a suspended web. Behind the suspended and descending web there is at least one pivoting air nozzle which directs a jet of air at the suspended web to avoid creasing the material as it is laid. The pivoting air nozzle fans the jet of air across the downwardly descending web as it falls. Means are provided for varying the speed of the pivoting nozzle as the speed of the laying carriage varies.

  • Patent number: 4516760
    Abstract: The apparatus comprises a laying carriage which travels over a laying surface to deposit web material on the surface. The web material falls as a suspended web. Behind the suspended web there is at least one air nozzle which directs a jet of air at the suspended web, so avoiding creasing of the material as it is laid. The nozzle is on the end of a flexible air supply line which provides for easy adjustment of the position and orientation of the nozzle.

  • Patent number: 4419820
    Abstract: A movable guide system for material or cloth cutting out machines which can be easily manipulated and thereby facilitate the rapid filling of orders. The movable guide system employs the rotary arm machine principle, in which a frame extends over a laying table in a portal-like manner, wherein a carriage is rotatably fastened to the frame generally centrally above the laying table, wherein the carriage is retained at its pivot point displaceable relative to the frame and in which the cutting out element is fastened to one end of the carriage. The cloth cutting element is in each position thereof displaceable and rotatable with respect to the laying table, so that each point of the work area can be reached from every other point on the work area and whereby the motion of the cutting out element can also be easily carried out manually.

  • Patent number: 4280782
    Abstract: An air cushion table for transporting layers of laminar material of loose consistency, e.g. layers of fabric, with compressed air lines disposed in the table plate and connectible to a compressed air source, the compressed air lines discharging with upwardly directed exit openings from the surface of the table plate. The compressed air line in the area of the exit opening is in each case provided with an insert made of porous material which occupies the cross-section of the compressed air line.
