Abstract
A mechanism for feeding weft yarn stock bobbins to a loom includes a bobbin frame (3) for at least two stock bobbins (4) which may be fitted to bobbin holders (38) having longitudinal axes (L) which may be aligned on a common yarn guide member (6). The bobbin holders (38) are each formed on a bobbin carrier (10, 10') intended for receiving one of the stock bobbins (4) and able by means of a holder (30) of a charging mechanism to be fastened to the bobbin frame (3) and removed from the bobbin frame, the bobbin carrier having a yarn guide unit (45) for feeding the piece (A) at the start of the weft yarn (5) wound onto this stock bobbin (4) to the common yarn guide member (6). The yarn guide unit (45) is formed on a carrier part (44) able to swing between a normal position suitable for seizing the starting piece (A) and a deflected position in which in an operating position of the bobbin carrier (10, 10') predetermined on the bobbin frame (3) and aligned with the yarn guide member (6), the yarn guide unit (45) may be set in a definite yarn delivery position and may be brought together with the yarn guide member (6). A simplification of the charging process and delivery of the yarn is accordingly achievable.
