ABSTRACT:
An apparatus for tensioning warp threads of a loom comprises a warp beam from which the warp threads are withdrawn by means of a support beam and a deflection beam. The deflection beam is secured to the support beam by means of bending springs acting in the direction of the deflected warp threads. The bending or deflection length of the bending springs is adjustable for preselected setting of the warp thread tension in that the bending springs are supported at their bending or deflection side by means of a bending-resistant support plate which is adjustable in lengthwise direction. These measures provide for a purely mechanical, simple, easily adjustable and functionally reliable tensioning apparatus which is particularly suitable for the pile warp of a Terry weaving machine.
