Definitions
- the invention relates to a weaving machine, in particular for weaving machines that process hose heads, with an upwardly open trough space and a clamping device mounted therein near one end for clamping an exchangeable weft thread carrier.
- Shuttles of this type for weft spools have long been known in numerous embodiments.
- Such weft bobbins can only be used for a limited length for weaving reasons and, due to the continuous length of the bobbin core, can only take up a relatively small amount of weft thread.
- the weft length carried is therefore used up in a very short time, so that the change points in the fabric are so close together that the points of overlap of the weft end of the old weft bobbin and the weft thread start of the new weft bobbin over the Tissue width must be distributed.
- weft insertion the weaving machine has to be switched off and part of the last weft thread inserted has to be pulled out and cut through the upper compartment, whereupon the shooter loaded with a new weft yarn bobbin is pushed in by about 1 to 2 cm through the upper compartment and conveyed by hand into the shooter box, so that the weft ends in the fabric lie slightly overlapping together.
- This way of working is not only very labor intensive, but also leads to a considerable downtime of the weaving machine, so that it can only be operated with an efficiency of 50 to 60%.
- the straight through the trough space thread insertion slot with the aligned brake slot of the thread brake enables a reliable automatic insertion of the thread of the new weft carrier.
- trough space 11 has an elongated, upwardly open trough space 11 with smooth walls and a clamping device 12 arranged near one end, each with two resilient clamping jaws 15 located opposite an associated side wall of the hunters 10.
- a thread brake 13 is inserted in the weaving machine 10.
- a thread insertion slot 16 recessed on the upper side in the adjoining end section of the shuttle 10 is aligned with the longitudinal axis of a hose cop inserted into the trough space 11, which has a conical cop end 1 designed for external take-off and an attachment part 4 firmly integrated in the cop thread winding, the coaxial part of which extends outward projecting end pin is clamped in the jaws 15 of the clamping device 12 so that the hose cop is cantilevered in the trough space 11 is held aligned.
- the cop thread 17 originating from the hose cop is inserted into the thread insertion slot 16 and a slot of the thread brake 13 that is aligned therewith.
- a conventional threading device 14 branches off from the thread insertion slot 16, into which the bobbin thread 17 automatically engages when the shooter 10 moves with the clamping device 12 lying at the shooter end.
- the trough space 11 has a section which remains free between the thread brake 13 and the bobbin end 1, into which a thread gripper described in the applicant's parallel European patent application relating to a hose bobbin replacement device is lowered by the same filing date when the bobbin is automatically changed so that the bobbin thread 17 is automatically the thread brake 13 and the thread insertion slot 16 is inserted.
- the thread brake shown enlarged in FIG. 2 has two brake shoes 21 and 22 which are guided in a housing 20 to a limited extent by guide pins 23 and which form a brake slot between them.
- the brake shoes 21 and 22 are pressed against one another by coil springs 25, the spring force of which can be adjusted by adjusting screws 26 which can be rotated in threaded bores of the housing 20.
- each spring cage 27 with a cage slot 29 aligned with the brake slot between the brake shoes 21 and 22.
- Each spring cage 27 contains two on the opposite sides of the cage slot 29 on guide pins 28 arranged locking springs 30 with extended free end portions 31 which pass through the cage slot 29 transversely in the opposite direction and can be deflected downward against the force of the locking spring 30 by pivoting.
- the exchange of the hose cop is advantageously carried out by means of a hose cop exchange device which is shown in FIG parallel European patent application of the applicant of the same filing date described.
- the holding pin of the largely expired copos residue which is held resiliently in the clamping jaws 15, is ejected from the web shooter 10 by means of a cop ejecting punch which can be extended through a through opening in the bottom of the shooter 10, and then a new hose cops stamp is used by means of a cop press stamp pressed into the jaws 15 with its mounting pin.
- the cop thread 17 of the new hose cop is gripped by two spaced thread grippers, one of which is sunk into the section of the trough space 11 between the thread brake 13 and the hose cop and the other is lowered outside the shooter end, so that the cop thread 17 stretched taut between them the thread insertion slot 16 as well as the brake slot and the cage slots 29 of the thread brake 13 is inserted so far that the end portions 31 of the locking springs 30, which are initially pivoted downward, snap back into their dorsal position and thus prevent any unwanted sliding out of the cop thread 17 from the thread brake 13.
- the weaver who has been explained above with reference to a preferred embodiment can be modified appropriately by the person skilled in the art, provided that a thread insertion slot running straight from the trough space to the end of the shooter and a thread brake with an aligned brake slot are used.
