Patent ID: 7708541

Claim:
A coiling system for continuously forming coiled plastic tubing in preselected lengths, said coiling system comprising: a main tube shaft for forming plastic tubing into a helix, said main tube shaft having a longitudinal axis; a motor for rotating said main tube shaft about said longitudinal axis; a tube guide mounted with respect to a first point on said main tube shaft, said tube guide having a gap through which said plastic tubing is directed onto a predetermined point on said main tube shaft, said gap making an oblique angle with respect to said main tube shaft so that said plastic tubing may be wound onto said main tube shaft in a helical form; a heat source at a second point on said main tube shaft, said second point being downstream from said first point, said heat source being adapted to heat coiled plastic tubing at said second point; a cooling apparatus at a third point on said main tube shaft, said third point being downstream from said second point, said cooling apparatus being adapted to cool coiled plastic tubing at said third point to set said plastic tubing into a coiled form; a cutter at a fourth point on said main tube shaft, said fourth point being downstream from said third point, said cutter being adapted to cut coiled plastic tubing into preselected lengths by operating at preselected intervals of time; and a carousel for collecting preselected lengths of coiled plastic tubing cut by said cutter, said carousel having a plurality of shafts, each of said shafts being, in turn, aligned with said main tube shaft as said carousel is rotated for collecting a preselected length or coiled plastic tubing.
