A curing apparatus for curing a coating composition disposed on an optical fiber, the curing apparatus including a first light source and a second light source such that the second light source is spaced from the first light with a gap. The curing apparatus further including a first reflector and a second reflector such that the second reflector is spaced from the first reflector with the gap. Furthermore, a spacer is disposed within the gap, the spacer being formed of a material configured to reflect at least about 90% of light emitted from the first light source and from the second light source, and incident on the spacer, to an optical fiber such that the reflected light has sufficient intensity to cure a coating on the optical fiber.

Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

The present invention is related to the use of colored effect pigments for enhancing the infrared absorption capacity of colored polymers and to a method for enhancing the infrared absorption capacity of colored polymers.

The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.

A three-dimensional image forming system according to the present invention includes a conveying unit which conveys a heat-expandable sheet along a conveyance path, a heating unit which heats the heat-expandable sheet by irradiating the heat-expandable sheet with light, and a control unit which preheats the surroundings of the heating unit to a previously determined preheat temperature and then causes the conveying unit to convey the heat-expandable sheet.

The device relates to a device for producing plastic bodies wherein the device comprises a photopolymer curing unit comprising at least one radiation source with a selected radiation spectrum or spectrums for curing of light hardening photopolymer, a mold which mold is partially or wholly comprised of light transmissive material which material allows the passage of radiation of selected spectrum or spectrums for curing of light hardening photopolymers, and a fixture for securing and rotating the mold along one or more axis.

Light hardening photopolymer is introduced into the cavity of the mold and exposed to a selected radiation spectrum or spectrums for curing of light hardening photopolymers through the mold light transmissive material thereby hardening and curing the light hardening photopolymer whereupon the cured light hardening photopolymer is removed from the mold and the process repeated.

The device permits the production of photopolymer molded bodies or photopolymer coated bodies in a continuous or discontinuous process.

A thermally expandable sheet includes: a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material; and a second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material, wherein the second thermally expandable material further contains white pigment.

A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. A system for improving the application of film by transfer of electrostatic charge is also described. The preheating system and/or electrostatic charge system may be used to enhance binding and sealing properties of stretch films used for wrapping palletized products in a reduced temperature environment. Other embodiments of the preheating film system and electrostatic charge system, and methods for their use, are described herein.
