Abstract
A system for imposing a permanent bend in a length of tubing, includes a bend setting portion having surface, a groove extending inwardly of the surface, the groove having a dimension which is smaller than an outer dimension of a tubing to be bent therein a fixing element extendable to secure a tubing in the groove, and a heater configured to heat the bend setting portion to a fixing temperature.
Claims20
A system for imposing a permanent bend in a length of heat fixable tubing, comprising;
- a bend setting portion having surface;
- a groove extending inwardly of the surface, the groove having a dimension that is smaller than an outer dimension of a tubing to be bent therein;
- a fixing element extendable to secure a tubing in the groove;
- and
- a heater configured to heat the bend setting portion to a fixing temperature.
2 more elements
The system of 2, wherein the groove comprises;
- an opening in the surface of the bend setting portion;
- opposed side walls extending inwardly of the surface of the bend setting portion;
- and
- a first curved surface located inwardly of the groove and facing the opening and connecting to opposed inward ends of the opposed sidewalls.
1 more element
A method of bending a heat fixable tubing, comprising:
- providing a bend setting portion having surface;
- providing groove extending inwardly of the surface, the groove having at least one curve therein;
- providing a fixing element extendable to secure a tubing in the groove;
- pressing a length of tubing inwardly of the groove such that the tubing has the contour of the curve in the curve imposed on at least a portion thereof;
- heating the bend setting portion having the tubing therein to a setting temperature of the material thereof;
- and
- cooling the bend setting portion with the tubing and removing the tubing from the bend setting portion, wherein the curve of the groove remains in the tubing after the tubing is removed from the bend setting portion.
