Publication number: 20240117834Abstract: A fastener designed to reduce or eliminate stripping the fastener (e.g., as a result of camming-out during drilling of the fastener either into or out of a material). Also, a driver bit tip design to engage with the fastener, along with a tool designed to form the fastener, as well as a method of forming the fastener. In an example, the fastener includes a shank and a head on one end of the shank. The head comprises a recess pattern that includes one or more wing recesses with sidewalls that extend from the head towards the shank. The head further includes an overhang structure at a top end of the at least one of the sidewalls, the overhang structure extending laterally outward from the sidewall. A corresponding driver bit includes a complementary feature that engages with the overhang structure to inhibit cam-out.Type: ApplicationFiled: September 25, 2023Publication date: April 11, 2024Applicant: Phillips Screw CompanyInventors: Christopher M. Gallant, Gary E. Dilling

Publication number: 20240074544Abstract: A male touch fastener product with a resin surface and an array of spaced-apart male touch fastener elements carried on the surface. Each touch fastener element has a stem extending from the surface and a head disposed at a distal end of the stem and extending laterally from the stem to a distal edge overhanging the surface. The head, stem and surface form a contiguous mass of resin, the head. The distal edge has multiple toes extending laterally outward and varying in shape and size about the edge, with adjacent toes having facing, free-form resin surfaces defining crevices therebetween. The fastener element is particularly flexible and engages with very fine fibers.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: Luis Parellada Armela, Christopher M. Gallant, James L. Tardiff, Mark A. Clarner

Publication number: 20240001457Abstract: A debris ejector for a drilling tool is disclosed. The ejector may be provided as part of a tool assembly where the ejector is coupled with bit. In an example, a tool includes a cup and a drill bit passing through an internal void of the cup. The cutting end of the bit extends out the open end of the cup at a fixed distance, while an attachment end of the bit extends out the back of the cup. The tool further includes an ejector within the cup. The ejector spins with the bit and independently of the cup. In one example, the ejector includes ramped or angled wings that eject material within the cup. In another example, the ejector includes tapered wings with straight and/or angled walls that push material out of the cup through one or more holes of the cup.Type: ApplicationFiled: September 18, 2023Publication date: January 4, 2024Applicant: Phillips Screw CompanyInventors: Scott M. Filion, Gary E. Dilling, Christopher M. Gallant, Carl Marabello, JR.

Patent number: 11160334Abstract: A touch fastener product having a base sheet with a resin side surface and a male touch fastener element having a head disposed at a distal end of a resin stem and overhanging the base sheet. The head has an overall shape, as projected in a plane parallel to the base sheet, with a perimeter that defines spaced apart extremities corresponding to head sections of different engagement characteristics and disposed at different distances from a centroid of the overall shape. In one example, the head projection has a polygonal perimeter consisting of straight edges of differing lengths connected at radiused corners. In another, the perimeter comprises an unbroken series of at least three arc segments of different curvatures, with centers of the arc segments disposed at different distances from the centroid.Type: GrantFiled: August 18, 2017Date of Patent: November 2, 2021Assignee: Velcro IP Holdings LLCInventors: Christopher M.

Patent number: 10906214Abstract: A molding apparatus defining a processing direction includes multiple molding modules spaced apart in a lateral direction perpendicular to the processing direction and a common reaction surface. Each molding module includes a frame and a mold roll that defines molding cavities. Each mold roll defines a respective pressure zone in cooperation with the reaction surface and each mold roll is movable with respect to the reaction surface by controlled operation of the frame. Molten resin is introduced into the pressure zones and forced into the molding cavities to form arrays of fastener elements extending from base layers of resin formed on the surfaces of the mold rolls. The fastener elements are withdrawn from the cavities while stripping the base layers from the peripheral surfaces.Type: GrantFiled: December 10, 2019Date of Patent: February 2, 2021Assignee: Velcro BVBAInventors: Jerry G.

Patent number: 10532535Abstract: A method of forming a continuous sheet of pleated, hook-form, fastener product includes training a substrate about a pressure roll having an outer surface defining circumferential grooves. As the substrate approaches a nip between the pressure roll and a mold roll calendered with the pressure roll, a portion of the substrate is disposed within a corresponding one of the grooves between the pressure roll and a stationary horn extending into the groove whereby a longitudinally-extending pleat is formed in the substrate. The pleated substrate is then passed through the nip where resin regions are laminated to a side of the substrate opposed to the pleat.Type: GrantFiled: February 28, 2017Date of Patent: January 14, 2020Assignee: Velcro BVBAInventor: Christopher M.

Patent number: 10518525Abstract: Techniques are disclosed for connecting a printing plate to a print cylinder or surface. The techniques may be implemented, for instance, with respect to a printing plate, a print cylinder, a print sleeve, or some combination thereof. In an embodiment, a field of mechanical fasteners is provisioned on a printing plate, and a complementary field of mechanical fasteners is provisioned on a print sleeve or cylinder. The mechanical fasteners collectively operate to provide a mechanical bond or interface that inhibits lateral and rotational movement of the plate during printing operations, and can also be configured to manage backlash between engaging surfaces of the interface. In some cases, backlash management includes use of cushion effect integral with the mechanical bond itself and/or unidirectional and possibly angled fastener elements to provide a snugging effect.Type: GrantFiled: July 10, 2015Date of Patent: December 31, 2019Assignee: VELCRO BVBAInventors: Luis Parellada Armela, Josep M.

Patent number: 10463527Abstract: An ostomy belt has an elastic support membrane with a fibrous surface and an aperture for accessing a stoma. The aperture is formed by the user in a preferred location, and the area around the aperture is stabilized against stretch by applying a patch of relatively inelastic hook material to the fibrous surface about the aperture. An elastic membrane of an adhesive bandage is similarly stabilized about an opening in the bandage, by a hook patch that may have a flap for securing an IV tube.Type: GrantFiled: January 19, 2016Date of Patent: November 5, 2019Assignee: Velcro BVBAInventors: Christopher M.
