A technique for stable, high-speed treatment of reinforcement fiber. In a state where a unidirectional fiber bundle is held between a supporting surface of a support and a pressing surface of a resonator ultrasonically vibrating in a pressing direction perpendicular to the supporting surface, a pressed part of the unidirectional fiber bundle pressed by the pressing surface is moved in a longitudinal direction of the unidirectional fiber bundle. By doing so, the unidirectional fiber bundle can be stably treated at high speed when the unidirectional fiber bundle is opened or impregnated with a resin.

Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

An ultrasonic processing method and an ultrasonic processing device may include a controlling/regulating module, preferably a digital controlling/regulating module, which is integrated into a signal processing of the ultrasonic generator so that a plurality of generator data with respect to the ultrasonic generator are processible in the ultrasonic generator. At this, a power actual value P.sub.ist is compared with a power reference value P.sub.soll of the ultrasonic generator via a gap regulator in the controlling/regulating module to specify a position reference value POS.sub.soll of the sonotrode relative to the roll for adjustment of the power reference value P.sub.soll of the ultrasonic generator, and/or a power actual value P.sub.ist is compared with a power reference value P.sub.soll of the ultrasonic generator via an amplitude regulator in the controlling/regulating module to specify an amplitude reference value A.sub.soll to the ultrasonic generator for adjustment of the power reference value P.sub.soll.

An exchangeable ultrasonic welding module contains an ultrasonic transducer assembly (4) with a horn (5) and an anvil (7). The module contains a member (1) provided with a guideway (8) in a mating guideway (18) on the frame (10) of a filling tube (14). A locking element (11) secures the member (1) and the frame (10) in a fixed position relative to each other. The member (1) is provided with an element (2) for linear motion of a sliding carriage (3) and an adjustable stop (6) for restricting the carriage movement (3). The ultrasonic transducer assembly (4) is firmly affixed to the carriage (3), whereas the anvil (7) is affixed to the member (1). The frame (10) may contain an adjustable stop (9) for locking the member (1) in a defined position as the member is inserted into the mating guideway (18).

The ultrasonic welding device includes a rotary support mechanical assembly rotatable about a rotation axis and operable to support a sheet over a circumference centered on the rotation axis, the sheet being continuously supplied; and a horn and an anvil operable to sandwich the sheet supported over the rotary support mechanical assembly to thereby weld the sheet. The rotary support mechanical assembly includes a rotary member rotatable about the rotation axis, a plurality of sheet support members each having a support surface for supporting the sheet, and a mounting section for allowing the plurality of sheet support members to be attached to the rotary member in a state that the sheet support members lie on the same circumference about the rotation axis, and allowing attaching positions of the sheet support members to the rotary member to be adjusted in radial directions centered on the rotation axis.

A process for manufacturing a sheet molding compound carrier film including a first layer of material and a second layer of material sealed with each other along an edge. The seal is formed using ultrasound transmitted by a weld horn as both layers of material move along an anvil portion. The seal on the edge is suitably formed to protect the edge and build a weld to ensure moldable sheet molding compound flows to the edges of the carrier sheet, while providing a homogeneous mixture of glass and resin and also allowing air to escape.
