Forming fastener elements
10864662 · 2020-12-15 · ·

Arrays of male fastener elements are formed by molding preforms in cavities defined in one or more adjacent plates and shaped to mold preform arms that extend to a plate side, such as in a cross-machine direction of a continuous molding process. The preforms may be deformed to flatten their upper surfaces and lengthen the arms. Stems of preforms have molded side surfaces and each have width, measured in the longitudinal direction of the strip, that narrows with distance from the strip surface, and also narrows with distance from a parting line extending from the strip surface to the head between the arms.

FASTENER HAVING UNEQUAL NUMBER OF RAIL SEGMENTS AND POSTS

The fastener includes a backing and rows of rail segments and rows of posts protruding perpendicularly from the backing. The rows of rail segments and rows of posts alternate. Each of the rail segments has a base portion attached to the backing and a cap portion distal from the backing. The cap portion has a cap width that is greater than a width of the base portion, and the cap portion overhangs the base portion on opposing sides. A number of posts in one of the rows of posts is more than a number of rail segments in one of the rows of rail segments. Each of the posts has a height that is no greater than a height of the rail segments and a length that is different from the length of the rail segments. A fastening system that includes the fastener and a package that includes the fastener are also described.

MOLDED SURFACE FASTENER AND MANUFACTURING METHOD OF MOLDED SURFACE FASTENER

Provided is a molded surface fastener capable of stably having high engaging strength with respect to a loop member. The molded surface fastener of the present invention includes a base portion and a plurality of engaging elements provided with a stem portion and an engaging portion, and is formed of synthetic resin containing lubricant at 0.15 wt % or more and 1.00 wt % or less. A top end surface of the engaging element is formed to be flat, and the engaging portion has a hanging portion which hangs down obliquely downward toward the base portion.

Hook Fastener with Cap Cavity

A hook fastener includes a stem having two lateral edges, a first surface, and a second surface. A cap extends from an upper end of the stem, and the cap includes an upper surface, a first end, a second end, and a pair of overhanging portions. The upper surface of the cap is sloped between the first end and the second end. The first and second ends are at opposite longitudinal ends of the cap, and each overhanging portion extends in a lateral direction from the stem.

Touch fastener

A touch fastener having long and thin headed stems welded to and extending from, for example, a thin film, is made by orienting thin, hollow, drawn staple fibers between bristles of a brush, with no more than fiber ends sticking out of the brush, and then fusing a film to the fiber ends by direct welding. The fibers are then withdrawn from the brush as stems that are headed by heating their ends and allowing the resin to reform into an engageable head.

WRAPPING TAPE FOR REPELLING INSECTS AND LONG OBJECT USING SAME

An aspect of the present invention relates to a wrapping tape for repelling insects, the wrapping tape having a number of male engagement elements on a front surface of a tape, and a number of loop-shaped engagement elements on a rear surface of the tape, wherein the male engagement elements and the loop-shaped engagement elements can be engaged each other, and an insect repellent component is applied at least to the front surface of the tape and the male engagement elements.

MOLDED SURFACE FASTENER MANUFACTURING METHOD

In this molded surface fastener, plural engaging elements having a stem portion and an engaging head portion formed integrally on the stem portion are standing on the base portion, at least one pawl portion having a pawl width dimension narrower than a width dimension at a boundary between the stem portion and the engaging head portion is protruded on an outer peripheral edge part of the engaging head portion, and a back surface of pawl of the pawl portion is formed at different angles with respect to a back surface of head portion of the engaging head portion. Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

MOLDED SURFACE FASTENER MANUFACTURING METHOD

In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

Printed components and methods for making the same

The present invention relates to printed hook components for hook and loop mechanical fasteners, and other components such as on diaper chassis and other personal hygiene articles, and methods for making the same. The hook component comprises an organic polymer, a laser-sensitive agent, and a laser-induced print on the hook component created by the interaction of electromagnetic radiation with the laser-sensitive agent. The hook component can be used in a variety of applications, including mechanical fastening devices for personal hygiene articles such as diapers, adult incontinence pads, and medical gowns.
