Abstract
Abstract An apparatus and a method for readying filled supply bobbins for receipt by a winding machine. As each bobbin is delivered to the apparatus it is given a preliminary servicing and inspection, whereupon the bobbin is either rejected or further processed by having a tailing or inner end of the body of yarn severed and an unwinding or outer end of the yarn picked-up and formed into a bunch which is deposited by means of a ram in a hollow core of the bobbin for retention therein until subsequent retrieval at the winding machine. Next the bobbin is again inspected and either rejected or directed to the winding machine. The rejected bobbins may be deposited in a bin for manual inspection.
