ABSTRACT:
A system for transporting roving bobbins in a cyclic manner between roving frames (1), spinning frames (2) and a residual roving clear-off process, in which the roving bobbins are transported by a carrier (7) driven by a tractor (14) along a main rail (3) arranged to form an endless loop and working rails (4, 5, 6) branched from the main rail (3). Dogs (28, 29, 30) for representing the respective frame address or the respective working rail address are disposed on the main rail (3) and detected by a sensor (34, 35, 36) mounted on the tractor (14). A station (68, 69, 70) is disposed in the inlet area of the roving and spinning processes for transmitting a command issued from a central control unit (71) supervising the system to the tractor (14). The command is prepared in accordance with information regarding the conditions of the tractor (14) and of the respective frames (1, 2) and working rails (4, 5, 6) and includes information regarding the frame address and/or the working rail address requiring the transportation of a carrier (7).
