A manufacturing method of a resin article having a plurality of filamentous projections that are formed in a contact surface of a resin article body may include a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body, a heating step to heat the plate-shaped metal parts before or during the thrusting step, and a pulling out step to pull out the plate-shaped metal parts in a condition in which portions of the resin material of the resin article body is melted around the leading edges of the plate-shaped metal parts and in which melted resin portions are formed on unmelted portions of the resin material of the resin article body.

A frame rail assembly for supporting a tonneau cover comprising: opposing frame rails locatable on a cargo area of a vehicle, each of the opposing frame rails having one or more slots formed therein; and one or more inserts that fit within the one or more slots respectively; wherein the one or more inserts are shaped to fit substantially flush with a transverse cross-sectional profile of the opposing frame rails.

The molded surface fastener includes: a fastener member that has a plurality of engagement elements disposed upright on the first surface of a base portion, and a back member that is secured to the second surface of the fastener member and that is provided with a structure enabling passage of a synthetic resin. The base portion has a first base region of a predetermined thickness and a second base region formed to be thicker than the first base region, and the back member is secured to at least the second base region of the base portion. The adhesion strength of the back member to the fastener member is thus increased, enabling the back member to be held more firmly by the base portion.

A resin sheet having hair-like bodies arranged regularly on at least one surface of a base layer containing a thermoplastic resin, the surface with the hair-like bodies having a coefficient of friction, as measured according to KES, of 0.5 or more and 1.0 or less, a deviation of the coefficient of friction, as measured by KES, of 0.010 or more and 0.025 or less, and a deviation of roughness, as measured by KES, of 0.2 or more and 1.5 or less.

A molded hook surface fastener having a base plate and a large number of hook engaging elements projecting from a surface of the base plate, wherein both the base plate and the hook engaging elements is made of a resin mixture comprising polybutylene succinate (A) as a continuous phase and starch (B) as a dispersed phase, and satisfying the following requirements (1) to (3) simultaneously: (1) the dispersed phase comprises polyvinyl alcohol (C); (2) the starch (B) comprises a modified starch, and an amylose content of the starch (B) is 45% by weight or more; and (3) the hook engaging element tapers from a surface of the base plate toward a distal end portion and gradually bends from its middle such that the distal end portion faces a direction slightly approaching the surface of the base plate,
is produced without breaking the hook engaging element during the pultrusion molding and is decomposed in the natural environment and does not bring about environmental destruction when discarded.

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.

There is provided a touch fastener that has high followability to the relative movement of portions to be engaged and does not easily separate from a mating member, and thus is usable in a wider range of applications. In the touch fastener, all the elements, that is, first strands, second strands, and engagement elements are formed of a thermoplastic elastomer. Further, the plurality of first strands and the plurality of second strands are disposed to intersect with each other, and consequently, hole portions each surrounded by the two adjacent first strands and the two adjacent second strands are provided. Accordingly, it has a high elastic function, easily stretches, and has high followability to the relative movement of portions to be engaged.

A method for assembling an assembly comprising a tape (100) of retaining elements and a substrate (200), said method comprising the following steps: a step of forming a tape of retaining elements by dispensing a molding material into a molding device (1), so as to form a tape (100) of retaining elements comprising a base (51) presenting a bottom face (511) and a top face (512), the top face (511) of the base (51) being provided with retaining elements; and a step of applying a substrate (200) against the bottom face (511) of the base (51) prior to said bottom face (512) of the base (51) solidifying in such a manner as to cause the substrate (200) to penetrate at least in part beyond a plane defined by the bottom face (511) of the base (51) of the tape (100).

A method comprises using a three-dimensional additive manufacturing process to produce an interlocking volume, wherein using the additive manufacturing process includes depositing successive layers, each of which includes a first material distributed according to a first interlocking material pattern and a second material distributed according to a second interlocking material pattern, said second material differing from said first material.
