Seamless webbing loop of rock climbing quickdraw, textile machine and textile method

Abstract

The present invention discloses a seamless webbing loop of a rock climbing quickdraw, a textile machine and a textile method. The seamless webbing loop of a rock climbing quickdraw contains a plurality of tubular webbing layers, one surrounded by another, among which there is at least one indication layer. The indication layer is adjacent to the outermost one among the plurality of tubular webbing layers or is the innermost one among the plurality of tubular webbing layers. Such a multilayered structure of the webbing loop enhances the strength of the webbing loop for the quickdraw, but does not cause a seam to the webbing loop. Further, the indication layer contained in the webbing loop functions to remind a user of timely replacement of the webbing loop when the webbing loop is worn, and thus the webbing loop is safe in use. With the movable spindle assembly arranged on the textile machine, it is convenient to remove the webbing loop from the textile machine. In addition, the webbing loop disclosed in the present invention has a simple structure without any seam, and is strong, safe and durable.

1 . A seamless webbing loop ( 1 ) of a rock climbing quickdraw, comprising a plurality of tubular webbing layers, one surrounded by another, among which there is at least one indication layer ( 4 ), which is adjacent to the outermost one among the plurality of tubular webbing layers or is the innermost one among the plurality of tubular webbing layers. 
     
     
         2 . The seamless webbing loop of  claim 1 , wherein, the indication layer ( 4 ) is a solid webbing having a rectangle or elliptic cross section, and is the innermost layer among the plurality of webbing layers of the webbing loop. 
     
     
         3 . The seamless webbing loop of  claim 1 , wherein, the indication layer ( 4 ) is a hollow tubular webbing section with a warning sign, and the hollow tubular webbing section is adjacent to the outermost webbing layer among the plurality of webbing layers. 
     
     
         4 . The seamless webbing loop of  claim 3 , wherein, the hollow tubular webbing section has a single-layer structure. 
     
     
         5 . A textile machine for weaving a seamless webbing loop of a rock climbing quickdraw of  claim 1 , comprising a base ( 5 ), pads ( 6 ) arranged on the base ( 5 ), and a spindle ( 7 ) arranged on each of the pads ( 6 ), wherein, the base ( 5 ) is provided with an opening ( 8 ), and a movable spindle assembly fitting with the opening ( 8 ) is arranged at the opening ( 8 ). 
     
     
         6 . The textile machine of  claim 5 , wherein, the spindle assembly comprises a base unit, a pad ( 6 ) arranged on the base ( 5 ), and the spindle ( 7 ) arranged on the pad ( 6 ). 
     
     
         7 . The textile machine of  claim 6 , wherein, the spindles ( 7 ) are arranged in a circle, and a webbing passage ( 9 ) running through the base is arranged at the center of the circle. 
     
     
         8 . The textile machine of  claim 6 , wherein, a gear shaft connecting with a plurality of gears is arranged in the base unit, one end of the gear shaft is connected with the spindle ( 7 ), and the other end of the gear shaft is connected with a power unit of the textile machine, so that the spindle ( 7 ) is driven by the power unit, and the base unit is hinged to a side of the opening ( 8 ) and is snapped on the other side of the opening ( 8 ). 
     
     
         9 . A textile method for weaving a seamless webbing loop of a rock climbing quickdraw using a textile machine of  claim 8 , wherein the textile method comprises steps of:
 S1) starting the textile machine to weave a hollow webbing having a length;   S2) guiding a woven end of the hollow webbing to the outside of the textile machine and then inserting the woven end into a weaving end of the hollow webbing via the webbing passage ( 9 ) at the bottom of the base ( 5 ) of the textile machine to form a loop, continuously weaving along the loop to sheathe the hollow webbing with a plurality of webbing layers, and tying the weaving end to the outermost webbing layer to form a woven webbing loop of the rock climbing quickdraw, where an indication layer is adjacent to the outermost webbing layer; and   S3) unsnapping the spindle assembly at an opening of the base of the textile machine, and removing the woven webbing loop.   
     
     
         10 . A textile method for weaving a seamless webbing loop of a rock climbing quickdraw using a textile machine of  claim 8 , wherein the method comprises steps of:
 S1) starting the textile machine to weave a tubular webbing having a length, which sheathes a solid webbing;   S2) guiding a woven end of the tubular webbing sheathing the solid webbing to the outside of the textile machine and then inserting the woven end into a weaving end of the tubular webbing via the webbing passage ( 9 ) at the bottom of the base ( 5 ) of the textile machine to form a loop, continuously weaving along the loop to sheathe the tubular webbing with a plurality of webbing layers, and tying a weaving end to the outermost webbing layer to form a woven webbing loop of the rock climbing quickdraw; and   S3) unsnapping the spindle assembly at an opening of the base of the textile machine, and removing the woven webbing loop.
