Provided is a resin composition capable of forming a coated product that exhibits low adhesion to a metal roll during production and is superior in oxygen barrier property and capable of forming a film or sheet superior in oxygen barrier property, impact strength under low humidity and color tone. The resin composition of the present invention contains 50 to 98 parts by mass of a modified starch (A), 2 to 50 parts by mass of a polyvinyl alcohol (B), 0.1 to 10 parts by mass of a polyoxyalkylene (C), and optionally 0 to 5 parts of a polyol plasticizer (D), wherein the total content of the (A), (B), (C) and (D) is 100 parts by mass.

A method and apparatus for a continuous compression molding machine. The continuous compression molding machine comprises a tooling die, extending through a heating zone and a cooling zone, a tooling sleeve, and a biasing system. The tooling sleeve corresponds to the tooling die and is for use in forming a thermoplastic composite part from a thermoplastic composite charge when the tooling sleeve with the thermoplastic composite charge is moved with respect to the tooling die through the heating zone and the cooling zone. The biasing system is configured to hold the thermoplastic charge at a first angle within the heating zone and hold the thermoplastic composite charge at a second angle within the cooling zone, as the tooling sleeve moves through the heating zone and the cooling zone with the thermoplastic composite charge. The first angle is different from the second angle.

The present disclosure provides an impregnation device for a fiber prepreg, which includes a film layer separation assembly, a hot pressing element, and a thermal barrier element. The hot pressing element is disposed beneath the film layer separation assembly. The thermal barrier element is disposed between the film layer separation assembly and the hot pressing element. The present disclosure also provides an impregnation method for a fiber prepreg.

Aspects of the present disclosure relate to methods and apparatuses for manufacturing absorbent articles, wherein discrete zones of protrusions may be formed on a substrate. In some configurations, the protrusions may be formed as hooks. When forming the discrete zones of protrusions, localized speed variances may be imparted to the advancing substrate to ensure the adequate time to form the protrusions is provided. As such, protrusions may be formed on portions of the substrate that have been temporarily stopped or slowed to relatively slow speeds. The substrates with zones of protrusions may then be incorporated into products, such as assembled absorbent articles, so as to place the protrusions in desired positions on the absorbent articles. As such, the methods and apparatuses herein allow for the use of hook forming techniques on substrates in article manufacturing processes that provide flexibility in such configurations without sacrificing desired manufacturing speeds.

Methods of manufacturing a conveyor belt (126) include applying a rubber composition (114) to a first side of fabric reinforcement (112) and scattering productive thermoplastic elastomer pellets (106) onto a second side of the fabric reinforcement to produce an uncured belt structure (120). The uncured belt structure (120) is continuous fed into a double belt press (116) to press the productive thermoplastic elastomer pellets (106) together with the fabric reinforcement (112) to produce an uncured belt (128). Uncured belt (128) is then heated in the double belt press (116) to a temperature of at least 300° F. and maintained in the double belt press (116) under a pressure of at least 12 psi and a temperature of at least 300° C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).
