Rotary tubes have been used. The can or lap is deposited synchronously with the stretching process or in an orderly fashion, for example circulating in zywerk or not, depending on whether a cloidal layers on a depositing plate in cans. or around a rod, this being a depositing device. For depositing the twisted sliver device to maintain the desired real rotation 5 is followed by a jug. It is also Driven at a corresponding speed, it is possible for twisted sliver to pass through a winding (Joliannsen, “Winding up the history of the textile industry.
