摘要:
A protective sleeve (1) comprises sheets (2, 3, 4, 5) of a flexible material. The sheets (2, 3, 4, 5) are arranged in four layers on top of each other, each sheet (2, 3, 4, 5) having a top edge, an opposing bottom edge and two mutually opposed side edges connecting the top edges and bottom edges. Each respective sheet (2, 3, 4, 5) is attached to an adjacent sheet along at least two opposing edges of the respective sheet so as to form a front pocket (7), a central pocket (8) and a back pocket (9). The central pocket (8) is open at the top edges and is adapted to contain a disc-shaped recording medium (10). The bottom of the central pocket (8), determining the depth into which the recording medium (10) may be inserted in the central pocket (8), is defined at a substantial distance (D) from the bottom edges of the sheets (2, 3, 4, 5). A holder comprises a flat bottom element carrying a plurality of ribs forming between them slots, in which are provided lateral projections for engagement with a fastening strip of the sleeves.
摘要:
A device for dispensing two-sided adhesive pieces of an adhesive (3), comprising a support (7) for a roll (1) of a carrier strip (2) carrying a strip or pieces (3) of a two-sided adhesive. The roll (1) can rotate in a support (7) at the dispensing of carrier strip (2) and adhesive (3), a free end of the carrier strip being pulled out of the support (7) along a wall portion thereof. The wall portion is at a downstream end, relative to the movement of the carrier strip during dispensing, provided with a tear-off edge (22a) for tearing off the carrier strip (2). The tear-off edge (22a) has a V-shape, which is concave relative to the wall portion.
摘要:
The device has a roll (1) of a carrier strip (2) holding pieces (3) of two sided adhesive tape and wound on a hub (5) with an outer radius and provided with a circular cogging (6), a support (7) for the roll (1) comprising a stub shaft (9) with a direction of axis around which the roll rotates when dispensing tape pieces (3), a brake pawl (23) for engagement with the circular cogging (6), a pressure base (15) being in connection with the brake pawl (23) such that the engagement of the brake pawl (23) with the cogging (6) is released by pressure on the pressure base (15), a peripheral wall (10) extending along a part of the periphery of the roll (1), and a path for the carrier strip (2) extending past the pressure base (15) and along a part of the outside of the peripheral wall (11), the pressure base (15) comprising an outer sliding surface (16, 17) defining a part of the path for the carrier strip (2) with the two sided adhesive tape where the path at the pressure base (15) comprises a portion with a relative sharp curve (18) with a radius of curvature being essentially smaller than the outer radius of the hub. The two sided adhesive tape (3) is of a relatively rigid material, the two sided adhesive tape (3) being separated from the carrier strip (2) when the latter passes said relatively sharp curve (18) during advance.
