<p>A tufting machine comprises parallel looper (151) and knife (150) mechanisms independently driven via variable-stroke eccentric mechanisms (171) (172) and timing belt (167) (168) transmission arranged at least at one end but generally both ends of the machine, the driven parts of said mechanisms being longitudinally spaced from a parallel-disposed, vertically-adjustable jute or cloth bedplate (153) whereby the central area of the machine between the drive parts of the mechanisms and the bedplate is substantially free from driving shafts and ancillary driving components to give the operator substantial accessibility for maintenance and replacement purposes.</p> |
