Abstract
A yarn heating device for closed or open oven use has a plurality of elongate chambers for heating fluid. These are connected at one end to a reservoir for heating fluid having a horizontal connecting pipeline and one or more vertical pipes below it, these pipes having heating means. The chambers are connected at their other ends to a common collector by respective vertical pipelines which have separators near the collector, the separators having small orifices.
Claims9
A yarn heating device comprising in combination a plurality of elongate chambers to be heated internally by a vapourised heating fluid, a reservoir for heating fluid connected to one end of each said chambers, said reservoir comprising a horizontal pipeline which interconnects the chambers and at least one vertical pipe below and connected to said horizontal pipeline, heating means being provided to each said vertical pipe, a cylindrical collector for recovering vapours, a plurality of pipelines connecting the other ends of said chambers to said collector, said collector being above said chambers, and a separator element having two orifices of smaller diameter than the diameter of the pipeline in each said pipeline at the upper end thereof near the collector, each separator element including respective channels extending in opposite directions from said two orifices, one said channel terminating inside the collector and the other terminating substantially at a connection between the pipeline and the associated chamber.
