Abstract: A cutting device for bead core steel wire includes a first holder that holds a first blade body, a second holder that holds a second blade body, and a driver that moves one of the first holder and the second holder relative to the other of the first holder and the second holder. At least one of the first blade body and the second blade body is rod-shaped and includes a plurality of cutting edges arranged on a periphery of the at least one of the first blade body and the second blade body.
Abstract: An applicator head for cutting yarn into segments of yarn and depositing the segments of yarn on a deposition surface. The applicator head includes a single mechanism that moves the yarn towards said deposition surface and also cuts the yarn into segments.

Abstract: A method and a cutting device for the continuous cutting of fibers fed in fiber cables into fiber sections of particularly short length is disclosed. In order to avoid high friction forces between the formed knives and the fiber sections, and furthermore, to prevent excessive deforming of the fiber section during the transport between the knives, the knives are arranged at an offset to each other such that the fibers are initially cut into longer fiber sections, and into shorter fiber sections in a second step. The respective free space between the knives is increased due to the offset arrangement of the knives.
Abstract: A process for producing a flow of airborne fibers includes feeding a continuous length (2) of a thread bundle of fiber material from a stock (1) of fiber material through a roll press (4) which rotates at a rate of feed and with the thread bundle held fast in the nip between its rollers (11, 12), breaking off individual fibers from the thread bundle by means of a tearer (5), and carrying away the individual fibers broken off by the tearer by means of an air flow.
Abstract: Mechanically divisible multicomponent fibers have at least a component including poly(lactic acid) polymer and at least a second component including at aromatic polyester. The multicomponent fibers are particularly useful in the manufacture of nonwoven structures, and in particular nonwoven structures used as synthetic suede.
