  • Patent number: 5312062
    Abstract: A thread clamping device for a textile machine includes a clamping pad which is pressed against a clamping rib by a compression spring. The spring force can be adjusted, independent of other like devices associated with the machine, by an adjusting mechanism including a slider with an inclined surface supporting one end of the spring, wherein movement of the slider alters the precompression of the spring. The clamp is normally held open by a cam which overrides the spring, but when thread tension falls below an adjustable threshold, a tension monitor automatically activates the clamp.
