Abstract: A system for conveying a coiler can between a sliver producing fiber processing machine and a sliver consuming fiber processing machine includes a carriage for accommodating the coiler can; an electric motor mounted on the carriage for propelling the carriage; and a battery replaceably mounted on the carriage and being electrically connected with the motor for supplying electric current thereto. The system further includes a battery replacing apparatus having a manipulating mechanism for removing a battery from and for moving a battery onto the carriage and a supporting arrangement for supporting the battery during displacement thereof by the manipulating mechanism.

Abstract: An apparatus for supplying sliver-filled coiler cans to and withdrawing empty coiler cans from an intake track of a sliver-consuming fiber processing machine has a plurality of serially-arranged coiler can changers. Each coiler can changer receives at least three coiler cans in a standby position, a working position and a removal position, respectively. The working positions of the coiler can changers form a row having opposite first and second sides. The standby positions and the removal positions of the coiler can changers are all situated at the first side of the row of working positions. Each coiler can charger further has a drive for simultaneously shifting the three coiler cans thereon to move a first of the three cans from the standby position to the working position and a second of the three cans from the working position to the removal position.
