Abstract: A thread feeder with a thread-twisting preventive device for a knitting machine is provided. The thread-twisting preventive device includes at least a protective piece which is substantially cup-shaped having a wall and a coupling hole. The coupling hole allows the cup-shaped protective piece to be axially coupled to the spinning axis on the thread feeder, thus allowing the wall of the cup-shaped protective device to surround the spinning axis. Since the protective piece is a fixed piece that covers the exposed part of the spinning axis, broken threads will not be pulled by the spinning axis and twisted around the same. Production of fabrics thus will not be delayed due to broken threads twisting around spinning parts of the knitting machine.

Abstract: A spool protector with a vertically-extendable spool protector is provided. The vertically-extendable spool protector is extendable vertically to protect spools of various sizes from being flipped away from the rollers that support the spools. The spool protector includes a protection beam and a releasable fastening means for releasably securing the protection beam in desired positions. The releasable fastening means can be implemented in two embodiment. The first embodiment is a supportive piece having a pair of angled portions each forming a coupling hole therein and the second embodiment is composed of a securing frame and a screw mounted on said securing frame. When said releasable fastening means release the protection beam, the technician can freely adjust for a suitable position for the protection beam so as to protect spools of various sizes.
