Abstract: The present invention is designed to wind a long continuous fiber around a rotor and to cut the fiber in prescribed lengths by blades positioned at intervals on the circumference of a rotor. Scrapers rotate together with the rotor in order to scrape out the cut fibers displaced between the blades in accordance with the reciprocal movement of the rotor in the axial direction. The use of scrapers makes it possible to prevent the over packing of the cut fibers disposed between the blades, as seen in the case of conventional apparatuses, and to forcibly discharge the cut fibers from between the blades. Consequently, the cutting ability improves remarkably, specifically in cases where the fiber to be cut is especially short.

Abstract: A fiber crimping apparatus includes a relatively large diameter ring roller and an inscribed roller in contact with an inner surface of the ring roller. The two rollers are rotatable in the same direction at the same velocity and defined between contacting surfaces thereof a nip zone through which are to be fed bundles of fibers that are to be crimped therebetween. Each roller has thereon a respective side ring that is rotatable with the respective roller. The two rollers and two rings therefore define therebetween, at a downstream side of the nip zone, a stuffing box into which the bundles of fibers pass from the nip zone. A crimping resisting device is installed at a downstream side of the stuffing box and includes a movable member that is mounted to be movable in a widthwise direction of the stuffing box and of the bundles of fibers passing therethrough.

Abstract: A fiber crimping apparatus is disclosed which has an internally contacting type nip roller which consists of a ring roller and an inscribed roller rotating together in the same direction at the same speed. The apparatus is provided with a control groove formed on the surfaces of the ring roller and/or the inscribed roller holding the fiber bundle between them and which controls the thickness in the transverse direction of the fiber bundle to be crimped. As the fiber bundle in the nip zone is controlled in the transverse direction, the constriction of the fiber bundle is produced evenly in full width and the crimping process produces even waves and the apparatus is operated stably.

Abstract: Apparatus for crimping fibers comprises a ring roller of a comparatively large diameter which rotates in one direction and an inscribed roller which contacts the inner surface of said ring roller and which rotates in the same direction at the same velocity as the ring roller while holding bundles of fibers to be crimped between the two rollers and side rings which are situated on both sides of the place of contact of the two rollers and which rotate in the same direction at the same velocity as these rollers, and by forming the surrounding of a stuffing box by said rollers and rings.

Abstract: A conveyor having a conveying surface, which contacts an object to be conveyed, by plural coiled springs which rotate endlessly in accordance with the rotation of a main roller. The springs are trained over the main roller and a subordinate roller, which is provided at an appropriate distance from main roller and which rotates freely, in such a manner as the axis of spiral of each coiled spring runs in the direction of conveyance.

Abstract: A cutting device for a belt-like object is characterized by a pair of feed rollers and another pair of feed rollers which hold from both sides an object being supplied to be cut in succession. The rollers rotate at the same speed and are mounted in a horizontal direction respectively above and below the cutting position. The rotation of a main shaft driven by a motor is transmitted to a driving shaft of the pair of feed rollers placed above the cutting position through the main driving wheel of a one-way clutch. The rotation of the main shaft is also transmitted to a driving shaft of another pair of feed rollers placed below the cutting position through a subordinate driving wheel of said one-way clutch.
