In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.

The invention relates to a can containing a liquid and/or a gaseous medium which has positive pressure or develops such during transport or storage, wherein the cylindrical can shell of the can consists mainly of paper or cardboard material and is closed at the bottom with a bottom element and at the top with a cover element, wherein the can withstands an internal pressure of at least 5 bar, wherein the innermost layer of the can shell consists of a straight-wound barrier layer having a longitudinally extending folded seam, wherein the barrier layer is a prefabricated laminate made of an inner diffusion-tight barrier film or an inner diffusion-tight barrier laminate and an outer kraft paper layer.

An apparatus for manufacturing an annular or semi-annular composite component having a circumferentially-extending base and a flange, the apparatus including: a loom for weaving a woven preform of fibre reinforcement material for the composite component; a rotatable mandrel configured to receive and draw the woven preform through the loom for weaving; and a guide disposed between the loom and the rotatable mandrel, configured so that a woven preform drawn by the rotatable mandrel along a guide path under tension engages the guide to transition to a flanged profile at a lip of the guide before being received on the mandrel.

A hose forming apparatus is provided that can separate with minimum shape deformation when separating a hose after forming is complete. The hose shaping apparatus includes an insertion path configured to insert a hose in a longitudinal direction and to have a shape corresponding to that of the hose to be formed; and a fixing portion configured to fix the hose inserted into the insertion path, wherein the insertion path forms a straight insertion portion configured to insert a straight segment of the hose to be formed and a bending insertion portion configured to insert a bending segment of the hose, and the bending insertion portion has an additional angle further bent by 15 to 35 than an angle of the bending segment.

A method for making a bicycle crank arm includes (a) providing an inner frame unit, (b) winding a first bundle of unidirectional continuous fibers on the inner frame unit to form an intersecting pattern, (c) impregnating the intersecting pattern with a curable resin material to obtain an impregnated structure, and (d) molding the impregnated structure in a mold.

In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.

A paint roller manufacturing system includes a cover dispenser for continuously dispensing a windable width of paint roller cover fabric, a fabric supporting and advancing device for supporting the fabric and maintaining a width-wise dimension of the paint roller cover fabric as the fabric advances, a fabric coating applicator for applying a coating to the back side of the paint roller cover fabric while the fabric supporting and advancing device maintains the fabric in a width-wise dimension, and a compressing roller positioned downstream of the fabric coating applicator and configured to apply a compressive force on the coating after it has been applied to the back side of the paint roller cover fabric and while the fabric is supported by the fabric supporting and advancing device. In two-strip embodiments, first and second strip dispensers continuously dispense a first and second windable width of strip material. A guide system guides the first and second strip coming from the first and second strip dispensers to be wound about a mandrel and guides the coated paint roller cover fabric from the fabric supporting device to be wound about the first and second strips. An adhesive applicator is configured to apply adhesive on substantially all of the outer side of the first and second windable strips and positioned to apply adhesive to the outer side of the first and second windable strips upstream of a location where the coated paint roller cover fabric is wound about the first and second strips.

A method of sealing a wiring-harness includes the steps of: a) dispensing a length of a sealing-tape onto a platform, the sealing-tape having a first-surface and a second-surface opposite the first-surface. b) separating a plurality of wire-cables from a portion of the wiring-harness. c) applying the plurality of wire-cables to a first-half of the first-surface of the sealing-tape. d) folding a second-half of the sealing-tape over the separated plurality of wire-cables such that the second-half overlays the first-half. e) pressing the second-half of the sealing-tape such that the second-half contacts the first-half between the separated plurality of wire-cables, thereby forming a cable-band. f) coiling the cable-band into a generally cylindrical-shaped seal. g) compressing the cylindrical-shaped seal isostatically such that interstitial-voids within the cylindrical-shaped seal are reduced in size.

An apparatus for sealing a wiring-harness is also provided.

A method for producing a high-pressure tank that can, when forming a reinforcement layer following a previous reinforcement layer using fiber bundles, ensure the strength of the tank by reducing disturbance of the orientation of the fiber bundles. The method is adapted to form each reinforcement layer by winding fiber bundles while holding a preset tension for each layer, and includes a winding start step of stopping rotation of the tank liner upon completion of formation of at least one of the reinforcement layers, and, at the start of forming a following reinforcement layer, winding the fiber bundles at a tension smaller than a preset tension for the following reinforcement layer while alternately repeating rotation of the tank liner in the forward direction and the reverse direction, thereby forming a winding start portion of the following reinforcement layer; and a main winding step of winding the fiber bundles at the preset tension after the winding start step, so as to complete the formation of the following reinforcement layer.
