Provided are a method for producing a tank with an outer surface profile that allows a thin label to be easily and firmly attached to a surface thereof, and also such a tank. The method for producing the tank, which includes winding fiber bundles containing an uncured resin component in multiple layers around the outer surface of a liner in a first pitch width so as to form a fiber reinforced resin layer, further includes: winding fiber bundles in a second pitch width wider than the first pitch width so as to form a gap with a required width where no fiber bundle is present between adjacent fiber bundles in winding the fiber bundles to form an outermost layer; shaving off a tip end portion of a projection made of a resin that has cured after bleeding into the gap, with a portion of the projection in a predetermined height left unshaved; and attaching a label to a surface obtained through shaving off the tip end portion.

A system and method are provided for conditioning paint roller cover fabric inline in a continuous paint roller manufacturing process. The system and method provide an inline fabric conditioning unit upstream of the point in the process that the paint roller fabric cover strip is wrapped about the outer side of the outer strip, the fabric conditioning unit including a fabric conditioning device that conditions the paint roller fabric cover strip as it is being fed towards the outer side of the outer strip. The fabric conditioning unit may be used to perforate the fabric, to remove loose fibers from the fabric side of the paint roller fabric cover, to buff the paint roller fabric, and to orient the paint roller cover fibers. The continuous paint roller manufacturing process includes steps of feeding an inner strip and an outer strip towards a mandrel, wrapping the inner strip and the outer strip about the mandrel in offset relation, applying a strip adhesive to at least a portion of an outer side of the inner strip and at least a portion of an outer side of the outer strip, feeding a paint roller fabric cover strip having a fabric side and a backing side towards the outer side of the outer strip, the fabric side comprising loose fibers and attached fibers, forming a paint roller tube by wrapping the paint roller fabric cover strip about the outer strip at a point in the process after the strip adhesive has been applied to the outer side of the outer strip such that the backing side contacts the strip adhesive, applying compression to the paint roller tube, and cutting the paint roller tubes into like lengths.

An apparatus and a method enable continuous production of a reinforced plastic pipe using a transfer film. The transfer film moves at a predetermined speed in the longitudinal direction and is arranged to be in close contact with a circumferential surface of a base mold which winds glass fiber wound around the outer circumferential surface thereof using a filament winding method to mold a reinforced plastic pipe, such that the reinforced plastic pipe molded with the moving transfer film is moved forward, thereby being capable of continuously producing a reinforced plastic pipe with a desired length without breakage. The apparatus includes a rotary axial pipe; a base mold; a transfer film feeding part; and a transfer film withdrawing part. The method for continuously producing a reinforced plastic pipe includes a transfer film adhering step; a transfer film forced moving step; and a pipe cutting and separating step.

A method of manufacture of a product from a composite material is described, the method including winding a material onto a mandrel, monitoring the material, as it is wound onto the mandrel, to ascertain at least one dimension of the material being wound, and monitoring the mandrel as the material is wound thereon to ascertain the weight of the material being wound, and controlling the winding of the material onto the mandrel to take into account variations in the material being wound using the at least one dimension and the weight values derived during the monitoring. An apparatus suitable for use in the method is also described.
