摘要:
A reinforcement fibrous cord having excellent adhesive strength produced by impregnating a meshed cord fabric formed from warp yarns for reinforcement cords and weft yarns having a softening temperature or a melting temperature lower than any of the softening temperature, the melting temperature and the thermal decomposition-initiating temperature of the warp yarns, with adhesive agent, and heat-treating the fabric at the temperature equal to or higher than the softening or melting temperature of the weft yarn and lower than any of the softening temperature, the melting temperature and the thermal decomposition-initiating temperature of the warp yarns so that the weft yarns are self-broken while being fuse-adhered to the adhesive agent-impregnated warp yarns whereby projections caused by the broken residues of the weft yarns are formed on the warp yarns.

Verfahren zum Durchtrennen eines textilen Hohlschlauchs, das gekennzeichnet ist durch folgende Schritte: Einbringen eines Trennpapiers (T) in das Innere des Hohlschlauchs (H), Bereitlegen des Hohlschlauchs derart, dass er in zwei übereinanderliegenden Lagen (O, U) flächig vorliegt, Oberflächliches Anschmelzen einer ersten begrenzten Fläche (OF) der oberen Lage (O), Oberflächliches Anschmelzen einer zweiten, der ersten begrenzten Fläche (OF) gegenüberliegenden begrenzten Fläche (UF) der unteren Lage (O), Durchtrennen des Hohlschlauchs im Bereich der begrenzten Flächen (OF, UF).
摘要:
The invention concerns a method for making textile pieces, characterised in that it consists in applying a laser radiation on the textile material previously pleated or crumpled, so as to cut it along predefined contours and/or patterns. The invention also concerns garments and garment parts obtainable by said method.
摘要:
A method of making quick overlockings comprises the steps of manufacturing a band with at least one tubular portion in which at least two courses of the knitted fabric are made of a yarn capable of being melted upon increasing of its temperature beyond a predetermined value; folding back the band for obtaining a loop along the band itself with the two courses of meltable yarn disposed on opposite walls of the loop; inserting an edge of the knitted fabric to be trimmed into the loop; sewing the band to the edge in such a manner that the stitching does not affect the loop bottom included between the two courses of meltable yarn; heating the band beyond the melting temperature of the meltable yarn so as to separate the loop bottom from the rest of the band; slipping off the loop bottom from the band inside. The invention also relates to a tubular band intended to be folded for receiving the edge of the knitted fabric to which it is to be sewn and formed with the at least two spaced apart courses made of a meltable yarn.

摘要:
The invention concerns a device for producing preferably patterned textile strips (10') from a wide band (10) of a meltable material, the device comprising a heated cutting member (21) which may consist of an electrically heated wire. In order to develop an economical and compact device, a spring, advantageously a leaf spring, is associated as a pressure member with this heated wire. The leaf spring (22) has an aperture penetrated by the heated wire (21). Althrough the leaf spring (22) itself is not heated, its pressure region passes so close to the wire (21) that this region still acts on the strip edge areas which have been rendered plastic by the cutting process.
摘要:
The cutting head (8) is arranged on the carriage (6) via a securing foot (10) and has a cutter (36) penetrating the moving material web (2). To prevent damage during malfunctions and to facilitate maintenance and adjustment work, the securing foot (10) is secured to the carriage (6) via a ratchet device (14). The retaining force of the ratchet device in the direction of travel of the web of material (2) substantially corresponds to the force of the permitted cutting resistance of the cutter (36) in the web (2) in such a way that the cutter is disengaged if the cutting resistance in the web (2) is not the permitted value.
摘要:
An ultrasonic cutting device is applied to a weaving machine (11) downstream of a templet (20) and downstream of the take-up beam (84) of the machine. The newly formed fabric (T) is passed through an ultrasonic cutting device (50) which cuts it longitudinally. Tapes with perfectly smooth borders are obtained; non-thermoweldable fibres can also be cut.
