Abstract
A continuous extrusion and curing line has a linear hot air curing furnace which includes at least one UHF module which is selectively linearly movable along a length of the furnace.
Claims6
A continuous curing line oven includes:
- an elongated hot air furnace with a conveyor device in the interior thereof for conveying an extrudate along a length of said furnace through the interior thereof,
- at least one UHF module in the interior of said furnace and selectively linearly movable along a length of said conveyor device within the hot air furnace.
A method of curing a thermosetting material comprising the steps of:
- extruding an uncured thermosettable extrudate,
- carrying said extrudate through a hot air furnace by a conveying device,
- applying convective heat to said extrudate,
- applying UHF microwave energy to said extrudate, and
- further applying convective heat to said extrudate, wherein the point of application of said UHF microwave energy is selectively positioned along the length of said conveying device within the hot air furnace.
