Automatic sliver piecing after can change

Index

Also the sliver piecing has been automated in a few cases. The prerequisite are a rectangular can and a special auxiliary device on the operating robots. When a can is pushed out on the drawframe the end of the sliver must be positioned precisely at the front of the can lip. A suction arm on the operating robot grips the end of the sliver from the newly fed can and guides it between the intake roller and the feed table into the  spinning box. Automated sliver piecing actually is not used frequently, as the investment cost for such devices are relatively high.
