Abstract
A system is disclosed for the controlled depth scoring of conduits for the pneumatic transfer of particulate plastic materials comprising: a scoring assembly having interconnected drive power inlet means, motor drive means, drive coupling means, centering means and controlled depth score cutting means; and feed means connected therewith for longitudinally passing said scoring assembly through said conduits at a controllable uniform speed.
Claims5
Apparatus for the controlled depth scoring of a continuous spiral groove on the interior walls of conduits comprising a scoring assembly having inter-connected:
- (a) rotatable controlled depth score cutting means,
- (b) rotatable centering means,
- (c) rotary motor having a stator,
- (d) means for transmitting rotary motion from (c) to (a) and (b), and
- (e) an anti-rotational device, mounted to said stator and contacting the interior walls of said conduits during operation of said scoring assembly, wherein said contact is adapted to prevent rotation of said stator while allowing longitudinal movement of said stator within said conduit;
- and
- further comprising feed means connected with said scoring assembly for longitudinally passing said scoring assembly through the interior of said conduits at a controllable uniform speed, during rotation of said cutting means and its engagement with said conduit to thereby cut a spiral groove in said conduit.
