Abstract: A strip of drywall tape is simultaneously coated on its opposite front and rear surfaces as the tape is applied to a corner joint formed between a pair of abutting wall boards such as drywall panels. A tape guide provided on a drywall taping head guides a folded strip of drywall tape over a first reservoir of flowing drywall compound. The compound flows through the first reservoir and against the V-shaped front surface of the tape. The compound continues to flow over and around the front surface and over the rear surface of the tape and laterally into a pair of secondary reservoirs.

Abstract: This invention concerns a continuous manufacturing process of sections (11) or plates from soft matter (2) which is extruded under heat and encased by at least one strip sheet (3, 3′), said encased matter subsequently being calendered, shaped to the desired profile and finally cut into lengths, process which is particularly remarkable in that the matter used is a mixture containing a non-synthetic binder and water, so that the mixture becomes sticky by undergoing said heat treatment in an aqueous medium, which assures adhesion of the casing onto the matter during calendering, while the product undergoes at least one drying operation after said calendering operation. The binder is advantageously starch-based and the mixture may also contain a plasticizer, for example containing urea. The invention also concerns an installation for implementation of the process and the products thus obtained.

Abstract: The invention relates to a composite comprising a thermoplastic resin and a glass fabric that can be used in the form of a linear extrudate as a structural member or as a repair unit.

Abstract: In the manufacture of multichamber tubular containers it has been found that the inner divider walls should be bonded to the exterior wall by means of a band sealing method. In the band sealing method there is a band that contacts the upper film and a band that contacts the lower film that are to be bonded. In the present processes the upper band contacts the inner divider wall while the lower band contacts the exterior surface of the outer wall of the tubular container. In order to prevent the marring or otherwise putting a defect into the exterior surface of the outer wall the temperature of the lower band is maintained at a lower temperature than the upper band. This will decrease the temperature of the exterior surface of the outer wall and prevent imperfections in the exterior surface of the outer wall. The advantage is a multichamber tubular container without any imperfections in the exterior surface. This enhances the overall appearance of the tubular container.

Thus, even when a positioning error is produced due to a change in tension on the fastener tapes being processed, such error is limited to a small extent which is created only in the individual slide fastener length. Thus, the coupling elements and the first pin member and the second pin member can be molded precisely.
