ABSTRACT:
A drawing frame has a housing having an upper part and a lower part telescoping therewith, attachments for securing the parts together at any of a plurality of different vertically offset positions, a turntable in the lower part for supporting a sliver can and for rotating it about an upright axis, and an intake device in the upper part for pulling in and drawing slivers and for depositing the drawn slivers in the can. One of the parts is at least partially within the other part and the one part is formed with a plurality of vertically offset holes. The attachments are bolts engagable through the other part with the holes of the one part. These attachment bolts can simply snap in place, or can actually be screwed into threaded holes in the inner part.
