ABSTRACT:
A pile warp tension control method uses a pile warp tension control device capable of adjusting the tension of pile warp yarns according to a weave on a pile fabric loom. The pile warp tension control method involves setting a first pile warp tension amount for a pile weave section weaving mode for use in weaving a pile weave section, and setting second pile warp tension amounts for ground weave section weaving modes, respectively, for use in weaving ground weave sections, where the second pile warp tension amounts are higher than the first pile warp tension amounts. The control method further involves gradually increasing the tension of the pile warp yams from the first pile warp tension amount toward a selected one of the second pile warp tension amounts in a predetermined period after the change of the operating mode of the pile fabric loom from the pile weave section weaving mode to the ground weave section weaving mode. The control method next involves adjusting the tension of the pile warp yarns to the selected second pile warp tension amount after the end of the predetermined period.
