Abstract
A loom provided with a supply bobbin from which a weft thread can be drawn in which between the supply bobbin and a fluid pressure means for inserting the weft thread in a shed, there is located means for forming a loop of variable size for storage purposes. The loop-forming means is provided with a guide track which extends substantially transversely of a theoretical rectilinear weft thread track between the supply bobbin and the weft thread inserting means, and a guide member operably related to the guide track and being movable to and fro on the guide track and transversely of the theoretical rectilinear track away from the rectilinear track for guiding the weft thread and movable back again, with the guide track being arranged so that the return movement of the guide member is also transversely of the theoretical rectilinear track so that the weft thread is guided during the return movement from the guide member.
