A method and/or a machine is for tabbing a free end on a roll of sheet material. Converting a master roll of sheet material to the roll of sheet material and winding a first roll of sheet material onto a spindle at a winding position. Tabbing the free end of the roll of sheet material at a tabbing position. Where a tabber carrying a joiner are both in an initial position away from the first roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material. The joiner creates a tab with a combination of mechanical entanglement and heat welding. Returning the tabber and joiner to the initial positions. Doffing the tabbed roll of sheet material. The roll produced by the foregoing.

A mechanical touch fastener assembly (10,101) including two longitudinally continuous tapes (16), (18) carrying engaged fastener patches (12,12a), (14,14a,14b,14c). The first tape (16) carrying a series of first fastener patches (12,12a) arranged in a row along a length of the tape (16) and carrying a field of touch fastening features. Each first patch longitudinally spaced from adjacent first patches (12,12a). The second tape (18) carrying a series of second fastener patches (14,14a,14b,14c) carrying a second field of touch fastening features. The first (16) and second (18) tapes including a release liner (22), (24). The first (16) and second (18) tapes wound together to form a roll (60), with each of the first fastener patches (12,12a) releasably engaged to a respective one of the second fastener patches (14,14a,14b,14c) by inter-engagement of the first and second touch fastening features. As wound to form the roll (60), one patch of an engaged pair (25) has a leading edge (52,52b,52c) disposed behind a leading (50) edge of another patch of the engaged pair (25).

A cover member of the present invention is a cover member to be placed on a face of an object to prevent passage of a foreign matter through an opening of the face, the cover member including: a protective membrane having a shape configured to cover the opening when the cover member is placed on the face; and a first substrate layer joined to one of principal surfaces of the protective membrane. The first substrate layer has a laminated structure including at least two substrate films, and is positioned between the protective membrane and the face when the cover member is placed on the face. The at least two substrate films include a non-foam film and a foam film. The cover member of the present invention is suitable for improving the peelability from a member supply sheet.
