Fabric cutter for non-thermoplastic fibres - feeds thermoplastic powder to cutting region and applies thermal shock, e.g. by ultra-sound or laser

The cutting of fibrous material which does not melt easily is effected to avoid the unravelling of cut edges, using ultrasonic or laser beam techniques. The method includes (a) applying a thermoplastic powder material to the cutting region, and (b) applying thermal shock to the localised area, sufficient to destroy the fibres of the material, and melt the powder on eithe rside of the cut, and (c) pressing the cut edges while the fused thermoplastic powder is still soft. Woven or non-woven fabrics have a tendency to unravel, after cutting, and normally require a sewn hem. The method of the invention disposes of the sewn hem, and provides a thermo-cutting technique applicable to non-fusible or non-thermoplastic fibres.

LASER MACHINING

Conventional laser machining methods have disadvantages when used with relatively sort materials. To overcome this, a high power laser (1) has its output directed via a lens system (2) into one end of an optical fibre (3), the other end of which is placed near the work. As a hole is made the fibre end descends into the hole which is slightly wider than the outside diameter of the fibre. This gives a good cylindrical hole. The device can also be used to scribe lines in the surface of the material. ...

Marking of fabrics and other materials using a laser

A unique method imparts laser induced patterns and other designs on thin fabrics and leathers. The method uses a laser beam to slightly penetrate the surface of the product at a controlled specific speed. The laser beam is directed at the product either directly or through mirrors, shutters or lenses. The speed of the laser beam relative to the surface of the product is controlled within a predetermined range. Specific identification and control of this relative speed for a particular product are the keys to overcoming technical barriers which have prevented such use of lasers in the past. Preferably a computer is used to provide a signal to a drive mechanism to control the relative speed. The drive mechanism can control movement of the laser, the product, a mirror or a lens.

CUTTING YARNS

An excimer or ablation laser is used to cut selected, e.g. warp yarns in a fabric, particularly in joining the ends of a papermaking fabric to make the fabric endless. Optical imaging and electronic guidance of the laser projection is used, and the laser beam may be directed down a probe tube (20), which extends into the fabric and is shaped to push aside yarns to enable the laser to be directed to a target yarn. The laser may also be used for welding yarns in a second stage of the fabric joining process.

The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.

The holes (22) are formed by removal of the material therefrom with fracture of the fibers, for example by pressurized water jet machining, the arrangement of the fibers in the preform having holes being substantially unmodified with respect to to the initial arrangement before forming the holes. The CVI densification gradient is thus very small.
