Abstract

This invention is directed to a method and apparatus for transferring heat between two bodies separated by a narrow space and movable relative to each other, the temperature of one body dependent upon the temperature of the other body.

Claims

1. An apparatus for transfer of heat between a first body and a yarn transport roller mounted on a driving shaft rotatably connected to said first body, said first body and yarn transport roller being variably movable relative to each other, said first body and yarn transport roller having co-operating transfer surfaces adjacent and closely spaced to form a transfer gap, said transfer surfaces being symmetric and axially equidistant and perpendicular to the axis of rotation, comprising means for heating said first body, spring means for axially urging the yarn transport roller toward said first body, and means for supplying a non-solid interspacial substance under pressure to said transfer gap to transfer heat from said body to said yarn transport roller and to cause the pressure of said non-solid interspacial substance to vary inversely with width of said transfer gap.

2. An apparatus according to claim 1 wherein said first body is provided with at least one flow restriction ending in the transfer gap whereby the non-solid substance is supplied from a pressure source.

3. An apparatus according to claim 2 whereby the pressure source is constant.

4. An apparatus according to claim 1 wherein said yarn transport roller is slidably attached on said driving shaft.

5. An apparatus according to claim 1 and further comprising means mounting said roller for tilting movement relative to the first body.

6. An apparatus according to claim 5 wherein the roller is mounted on a driving shaft at least part of which has a low flexural rigidity.

7. An apparatus according to claim 5 wherein the roller is mounted on one end of a short driven shaft connected at the opposite end with the driving shaft by a coupling, said coupling comprising a coupling half section having internal teeth mounted on the driving shaft, and a coupling half section having external teeth mounted on the short driven shaft said external teeth meshing with said internal teeth.
