ABSTRACT:
Automatic device for loading and unloading identical objects e.g. textile or yarn supports, on at least one machine and for conveying said objects between the machine, a take up area and a feed area for use particularly in the automatic doffing and donning operation of textile machines, and more especially, machines with vertical spindles, such as synthetic yarn drawing machines.
The device includes at least two groups of cars having gripping and laying means. The first group is used for removing treated objects e.g. bobbin with yarn winding thereon, from the machine and conveying them to a take up area, the second group for conveying objects to be treated e.g. empty bobbins, from the feed area and positioning them on the machine.
