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.

This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

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.

A system of attachment surface structures that find their best use in the form of repeatedly removable straps and bands for securing one object to another. The surfaces are preferably constructed of narrow sheets of flexible polymer plastic materials having generally high tensile strength. A first embodiment includes shaped parallel ridges on one surface that interlock with mating parallel ridges on an opposing surface. These parallel ridges may be double sided (interlocking on both sides of each shaped ridge with the next shaped ridge on either side) or single sided (interlocking with a single ridge oriented 180 degrees from the first). Further embodiments include an array of shaped posts of various regular geometric shapes that interlock with an opposing array of identical posts.

A strap may include fabric and may be configured to attach an electronic device such as a wristwatch or head-mounted device to a user's body. The fabric strap may include a closing mechanism that attaches a first fabric portion of the strap to a second fabric portion of the strap. The closing mechanism may include a first array of posts on the first fabric portion and a second array of posts on the second fabric portion. The first array of posts may engage with the second array of posts to attach the first fabric portion to the second fabric portion. The posts may be printed on the fabric using additive manufacturing equipment, which allows the closing mechanism to be integrated into the fabric. Each post may include a rigid core and soft covering that deforms when the posts are engaged.
