  • Patent number: 4403379
    Abstract: A chain for a tentering frame includes links which carry so-called tentering hooks and needles for holding a fabric web to a movable conveyor forming the tentering frame. Each link (9) carries an intermediate support member (7) which holds at its free end a journal pin (3) below the margin of a fabric web (1). The journal pin (3) supports an arched bail (2) in a tiltable manner for movement between a working position and a rest position. The bail carries at its upper free end a further journal pin (12) which supports a tentering hook (10) in a tiltable manner. The first journal pin (3) further supports a needle bar (13) which is tiltable with its needles into a fabric penetrating position or into an inoperative position. The needle bar (13) preferably has a flat surface which cooperates with the tentering hooks (10) as a counter-holder when the needles are in a rest position.
