Abstract: In an embodiment, a long reinforcing material-attached profile strip (100) in which joint portions are formed at both side edge portions and to which a reinforcing material continuously formed in the longitudinal direction is attached is supplied, and mutually adjacent joint portions are joined to each other, thereby producing a spiral pipe (S). A curl-forming apparatus (3) includes a sending roller for the reinforcing material-attached profile strip (100) and a curl guide. Using the curl-forming apparatus (3), adjacent parts of the reinforcing material-attached profile strip (100) are subjected to plastic deformation to form spirals by being provided with arc-like curls having a radius of curvature substantially similar to or not greater than the radius of curvature of the spiral pipe (S). Accordingly, the spiral pipe (S) can be produced while suppressing the action of a restoring force that restores the reinforcing material-attached profile strip (100) to its original radius of curvature.

Abstract: A method for improving strength of the finished product in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method utilizes a substrate such as a polypropylene strip with grooves on its surface. The grooved substrate is fed onto a mandrel to form a tube. Adhesive is applied upon the grooved surface of the grooved substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The hardened adhesive in the grooves may operate to reduce the hoop-force which would otherwise tend to unwind the wound substrate. The method in certain embodiments provides a reduction in cost and weight of the finished product.

Abstract: A method of continuously forming heated conduit (17) includes performing a tape (31) for winding onto a spiral pipeline former. At least one conductor (4,5) is positioned adjacent to the centreline of and parallel with a thin polymer ribbon. The ribbon is folded in half to encapsulate the conductors. The folded ribbon is thermally welded to itself. The folded, welded, ribbon is passed through a creaser, which forms a crease midway across the folded ribbon. The creased pre-formed ribbon is formed into a conduit in a continuous process on a spiral pipeline former (24).

Abstract: A method of manufacturing a tubular film includes the steps of: winding a thermoplastic sheet film on a columnar member with at least two turns so that leading and trailing ends of the film are placed approximately on one normal line of an outer surface of the columnar member without overlapping each other; fitting a tubular molding member on the wound film; and connecting the leading and trailing ends of the film by heating at least the film, thereby forming the sheet film into the tubular film. The resulting tubular film has a high film thickness uniformity and suitable for a fixing film of an image forming apparatus.

Abstract: A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky. The body ply and a polymeric liner ply having a moisture barrier layer are then passed through a nip to adhere the liner ply to the body ply and are wrapped around a shaping mandrel to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface. The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape. A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped. Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply.

One end of the container is rolled outwardly to form a rim and exposing the inner surface of the liner ply, which comprises a heat sealable composition. A lid for the container, also having a layer of heat sealable composition, is placed adjacent to the exposed heat sealable composition of the container liner and heat sealed thereto. The heat seal has both an inner and an outer bead formed on either side of the heat sealed area, wherein the inner bead comprises a larger amount of the heat seal compositions than the outer bead. A method and apparatus for forming the heat seal is also provided.

Abstract: A method and apparatus for making paint roller covers by spirally advancing a thermoplastic tubular form past a plurality of electronic corona discharge heads arranged in a helical path around the tubular form to subject substantially the entire exterior surface of the tubular form to high frequency, high voltage sparks as the tubular form spirally advances past the heads to make substantially the entire exterior surface more receptive to adhesion when a uniform layer of epoxy adhesive is subsequently applied to the treated exterior surface of the tubular form. Next a fabric strip is spirally wrapped over the epoxy adhesive to bond the fabric strip to the tubular form. To make the exterior surface of the tubular form still more receptive to adhesion, the exterior surface may be preheated immediately prior to treating the exterior surface with high voltage sparks. Also, the fabric backing may be preheated immediately prior to spirally wrapping the fabric strip over the epoxy adhesive layer to minimize the amount of heat dissipated into the fabric. Further, a uniform pressure may be applied to the exterior surface of the fabric after the fabric has been applied over the epoxy adhesive layer to insure an even, uniform adherence of the fabric to the tubular form over substantially the entire surface area of the fabric backing.
