Abstract: A spool frame adapted for transmission of thread to a circular knitting machine comprising a framework subdivided into open section areas with each open section area provided with superposed tiers of semi-circular supporting elements on which are rotatably supported spool carrier elements. Thread guide means are arranged above the topmost semi-circular tier of spool carriers to control feed of the thread to the knitting machine.

Abstract: A filament monitoring device for knitwear manufacturing machines and of the kind having a filament guide arranged to move out of its operating position when a predetermined filament tension is exceeded and to be returned into the operating position with a force less than the breaking tension of the filament for automatic reapplication of the machine drive is, according to the invention, characterized by the provision of a guided slide member carrying only the filament guide and the armature of a magnet which holds the slide member in the operating position, and by a cable connection between the slide member and a return piston which is reciprocable in a compressed air cylinder and adapted to return the slide member to the operating position.
