Abstract

See full text

A machine for withdrawing or removing fibre staples from a set of bales of textile staples which can be displaced rectilinearly and alternately, with a carriage having a reciprocal vertical motion carrying rotary reels for removing said fibre staples from the bales is controlled by a device which comprises a plurality of detectors adapted previously to determine in the vertical sense sequential working zones for the carriage on the bales and an apparatus for automatically impressing a differential action of the carriage on the bales in relationship with the sequential preselected working areas. Thus the withdrawal of the fibre staples is obtained consistently with the compactness of the material contained in the bales without discrepancies in the production run and with a constant degree of bale-breaking.
