Glass fibre cutter - holds fibres without torsion twist for clean cutting to give optic fibre light waveguide lengths

摘要

The assembly to cut one or more glass fibres, as optic fibres for light waveguides, has a material advance and dampening component gp., a recessed tool with a diamond cutter, and holders to clamp and guide the severed light waveguide. The recessed tool (7) is firmly bonded to the advance and dampening gp. (1) with its horizontal movement. The clamps (17,18) are opposite the recessed tool (7) in succession and at a gap, along the glass fibre axis (16), at right angles to the diamond cutter (6). A clamp (18) is fixed to a base plate and a clamp (17) is attached to a push unit (2) moving along the glass fibre axis (16), working with a pusher fixed to it and a horizontal spring. Pref. The clamps (17,18) have fixed clamping supports (4,5) with one or more V-shaped grooves together with a clamping pad facing the supports which rotates round an axis together with pressure sections and a lever, working with a spring. The pusher is released and retracted through a pin at the advance and dampening group (1). In the operating position, the glass fibre (16) is held under a defined draw tension through the spring at the push assembly (2). ADVANTAGE - One or more glass fibres can be held free of torsion twist for cutting, esp. with a dia. of equal to or more than 80 microns, to give a clean cut without complex mechanical or electronic systems.
