Abstract
A knife block for a high-low cut pile tufting machine and which comprises a pair of laterally spaced apart and longitudinally extending channels in each of the side faces of the block. Each channel is adapted to securely mount a knife blade therein such that the pair of blades on each side of the block are aligned in the machine direction and are adapted to be independently removed, sharpened, and replaced.
Claims12
A knife block for a cut pile tufting machine having provision for accurately mounting a pair of knives which are adapted to operatively engage a looper in the formation of high-low cut pile fabric or the like, and comprising
- a solid body member having opposite ends and defining a longitudinal direction from end to end, opposite edge faces and defining a lateral direction from edge face to edge face, and opposite side faces,
- at least one of said side faces including a pair of laterally spaced apart and longitudinally directed channels, with each channel extending at least a substantial portion of the longitudinal length of said body member and communicating with at least one of said ends, and
- means for releasably securing a knife in each of said channels,
- whereby a knife may be secured within each of said pair of channels with the knives being laterally spaced apart so as to be adapted to concurrently engage a single looper in a tufting machine.
A knife block for a cut pile tufting machine having provision for accurately mounting a plurality of knives in pairs, with each pair being aligned in the machine direction to operatively engage a looper in the formation of high-low cut pile fabric or the like, and comprising
- a generally rectangular solid body member having opposite ends and defining a longitudinal direction from end to end, generally rectangular, parallel, opposite edge faces and defining a lateral direction from edge face to edge face, and generally rectangular, parallel, opposite side faces and defining a transverse direction from side face to side face,
- each of said side faces including a pair of laterally spaced apart and laterally aligned channels, with each channel extending the full longitudinal length of said body member and having a generally T-shaped cross-section, and
- means for releasably securing a knife in each of said channels,
- whereby a knife may be secured within each of said channels with the pair of knives on each side of the body member being laterally aligned and spaced apart so as to be adapted to concurrently engage a single looper in a tufting machine.
