Tensioning mechanism for a textile feed to a stepped operation digital textile printer
A textile feed for a stepped operation digital textile printer, comprises a textile feeding mechanism, and a tension storage mechanism. The textile feeding mechanism feeds the textile in a forward direction onto the printer, but is at the same time mechanically connected to a tension storage mechanism which is tensioned by the forward feeding. At the end of the feed step, the tension storage mechanism releases respectively stored tension to cause the feed mechanism to briefly reverse feed, thereby to pull the textile taut and take up any slack caused by the feeding step. The textile is thus kept taut, to allow effective digital printing by the printer.
