Patent number: 11020949Abstract: The method of making a laminate (100) includes stretching a thermoplastic layer (102) so that it plastically deforms, relaxing the plastically deformed thermoplastic layer (102) to reduce its tensile strain, and subsequently laminating the thermoplastic layer (102) to a substrate (104) to make the laminate (100). The stretching, relaxing, and laminating are completed in-line. The thermoplastic layer has a first surface and a second surface opposite the first surface, with the first surface of the thermoplastic layer bearing a plurality of male fastening elements. The second surface of the thermoplastic layer (100) is laminated to the substrate (104).Type: GrantFiled: December 19, 2016Date of Patent: June 1, 2021Assignee: 3M Innovative Properties CompanyInventors: Thomas J.

Publication number: 20200139612Abstract: The method includes stretching a thermoplastic layer so that it plastically deforms and decreases in width and subsequently laminating the thermoplastic layer to a substrate to make the laminate. The stretching and laminating are completed in-line. The thermoplastic layer has a first surface and a second surface opposite the first surface, with the first surface of the thermoplastic layer bearing a plurality of male fastening elements. The second surface of the thermoplastic layer is laminated to the substrate. In some cases, the thermoplastic layer decreases in width by at least 25 percent, and after the stretching, the thermoplastic layer has a width of up to 60 millimeters. In some cases, stretching is carried out by first and second rolls, and the second roll is faster than the first roll.
