Motorised tree-trunk sawing machine - uses band-saw and moving table with claws to grip tree-trunk and move it into saw

摘要

A sawing machine (1) with a motorised drive for a bandsaw (2) or circular saw has a manually fed table (5) supporting the workpiece (6) which may typically be a tree trunk. The table has a parallel operating pair of claws (8,9) and sharp pegs (10) which hold the work as the table is fed towards the saw. When the table is moved back to the starting position in readiness for the next cut, the claws pivot open against the force of tension spring (14) under the action of a draw cable (12) fixed at one end to the machine frame. The claws are held open by a catch (15) which is released by the operator to allow the jaws to spring up and bite into the work. ADVANTAGE - Simple, cost-saving design. Irregular sections are securely clamped. Safe operation of saw.
