Abstract
Abstract Heating apparatus for synthetic yarn processing comprising a pin or plate heater having a passive portion for attachment to a machine to provide and maintain predetermined alignment for a load contacting element of a removable and replaceable active portion. The thin load contacting element carries a thin etched foil heater and intimate resistance sensor bonded to its inner surface and is equipped with electrical leads to comprise the disposable active portion. The passive portion further thermally isolates the active portion to ensure high efficiency in transferring heat to the yarn load. Fast response inexpensive metals serve as the load contacting element so the compact low mass foil heater requires less power, responds quicker, and weighs and costs less than conventional yarn heaters.
