HEATING EQUIPMENT OF ROVING IN WINDING PROCESSING EQUIPMENT OF FILAMENT

摘要

PURPOSE:To constitute the title heating equipment so that a temperature of a roving can be held at a preset value at all times, by a method wherein a staying period of time of the roving in a heating box is made constant by moving at least an axial position of a roller out of a plurality of the rollers provided into the heating box, on which rovings are wound in order according to a feed speed of the roving. CONSTITUTION:A length of a prepreg roving 17 is a heating chamber 24a, that is, the length of the roving 17 extending from a roller 28 to a delivery eye 22 is varied according to the movement of both control rollers 29, 30 moving away or nearer. Thus the title equipment is constituted so that a feed speed (v) of the roving 17 is obtained by operating a detected signal from a speed detecting sensor 34 by a controller 35, both control rollers 29, 30 are moved away or nearer by sending a control signal to a servomotor 39 based on the value and a staying period of time (t) of the roving 17 of a unit length within a heating chamber 24a turns constant. Therefore, a heating time of the roving can be held at a preset value at all times.
