Abstract:
1. A device for producing at least two tubular belt bands which can be turned inside out, where each of the belt bands has two fabric layers on top of one another, and connected to each other in a longitudinal direction by woven hems, to form a cavity, warp threads of the layers have a uniform warp thread density over an entire length of the belt bands, the device comprising: a power loom having a shedding mechanism with a reed with parallel dents, a woof insertion device extending over an entire width of the power loom, a control unit for controlling the shedding mechanism, and an expander extending over the entire width of the power loom, the expander having a smaller diameter in a tubular area than in a hem area in correspondence with the belt bands to be produced, so that clamping pressure of the expander is substantially constant over an entire width of the woven fabric; and a thermal cutting device having cutting heads operative to cut out the belt bands in the hem area from the woven fabric web.
