ABSTRACT:
Slubbing, which is to be drawn, is pulled from cans (25), which are mounted behind a drawing frame. The frame comprises a double draw head section with devices for filling two cans (7 and 8), which are situated at respective filling stations. The filled cans (7 and 8) are then automatically replaced by empty cans (2): A slide (15 and 16) moves two empty cans (2) rectilinearly, counter to the working direction of the draw heads, into the filling stations and simultaneously moves the filled cans (7 and 8) rectilinearly in the same direction into two removal stations (13 and 14). Thus, the replacement of the cans (7 and 8) proceeds very rapidly and with a minimal gap between the filled cans (7 and 8) and the empty cans (2), which avoids the need for the frame to be stopped. A device (M and H) for controlling and driving the frame is accommodated in a rear part (6) of the frame housing which is situated on the side of the removal stations (13 and 14) facing the filling stations (7 and 8). The filled cans are then expelled laterally from the removal stations (13 and 14) by means of expulsion arms (17) through openings (19 and 20) on respective sides of the frame. The ground plan or working area of the drawing frame is therefore roughly rectangular and space-saving.
