Abstract: A method and apparatus for forming a skid-resistant surface on a thermoformed object such as a bed liner. The method includes forming a blank of extruded plastic material, abrading the surface with a wire brush, reheating the blank and thermoforming the blank to open the abraded surface of the blank. The apparatus includes an extruder delivery mechanism delivering a blank of sheet material to a wire brush which is turned by an electric motor at a speed slightly greater and in the same direction as the travel of the blank under the roller.

Abstract: A tube take-up apparatus is provided to handle a length of freshly extruded tube. The apparatus includes an elongated housing in which a pair of parallel, spaced-apart rollers extend lengthwise in a position just below the extruded tubing. The housing is removably mounted on an elongated supporting fin which is secured to the extruder at its near end, extends upwardly between the two rollers and substantially along the entire length of the housing, and is, in turn, supported on a fixed pedestal at its remote end. After the full length of tubing has been extruded, the housing and rollers as a unit are lifted with the tube from the supporting fin and replaced by an empty housing, to extrude the next tube, while the full housing is carried away to a dryer.

The steps include providing a blank having a head and a handle, wherein the head has one or more void spaces which divide said head into at least two segments, and injecting an elastomer into the void space at a temperature of at least about 245° C. thereby fusing the elastomer to the segments and forming a resiliently flexible joint. The elastomer is the sole mechanical link between the segments such that the segments can flex relative to each other and the elastomer can be stretched to about 120% of its unstressed length without separation of the elastomer from the segments.

Abstract: A golf ball having a cover composed of a polyurethane formed from a p-phenylene diisocyanate (PPDI) based polyurethane prepolymer is disclosed herein. The PPDI-based polyurethane prepolymer is formed from a PPDI and a polyol such as polycaprolactone. The PPDI-based polyurethane prepolymer is cured with a curative such as a 1,4 butane diol and glycol. The PPDI-based polyurethane cover may be either thermoset or thermoplastic. The PPDI-based polyurethane cover has a high flexural modulus at a lower hardness which gives a better feel yet maintains good distance, higher Bashore resilience, higher tensile strength, higher tear resistance, improved elongation, and better playability and control. These benefits and improvements are exhibited even though the cover of the present invention is thinner than those of conventional golf balls. The present invention also provides new golf balls having durable thin covers thereby enabling golf balls with large cores.

Abstract: A manufacturing method for a filter element having a filter portion and a flange portion formed along an outer periphery of the filter portion to protrude outwardly. First, a corrugated intermediate product having plural ridges of the filter element is formed by folding. Next, the flange portion is formed integrally with the filter portion by pressing an outer peripheral portion of the intermediate product at a high temperature. While the flange portion is formed, each of sides of the intermediate product extending in parallel with the ridges is restricted to a position corresponding to a shape of the filter element by plural forming jigs. Therefore, sides of the flange portion extending in parallel with the ridges are formed simultaneously when the flange portion is formed and do not need to be trimmed after forming. As a result, a material of the filter element is less wasted.
