DEVICE FOR TEMPORARY SOLIDIFICATION OF A SOFT PRODUCT

摘要

This invention relates to apparatus for temporarily rendering rigid a product of soft material of elongated form such as a rubber tube. In this apparatus, a tube of the product penetrates into a tunnel and issues therefrom after having been cooled by liquid nitrogen vaporized in an exchanger. A part of the nitrogen travels in counterflow and another predetermined part thereof travels in equidirectional flow towards a processing station. The invention is particularly applicable to braiding or winding rubber tubes, but is not limited to this field of use.
