<p>A method and apparatus are provided for bending thermoplastic, multiple channel tubing having a predetermined cross-sectional shape and a partition of a predetermined shape which separates the tubing into a multiplicity of channels. The method includes the steps of inserting the tubing into a hot liquid bath, maintaining said tubing in said bath until said tubing is bendable, bending said tubing into a desired shape, and supporting the softened tubing, including the partition, during the bending step. By these steps, and using the apparatus specially provided, the bending procedure substantially maintains the predetermined cross-sectional shape of the tubing while also substantially maintaining the predetermined shape of the partition as well as its proper orientation with respect to the rest of the tubing.</p> |
