The composite structure has a Shore A hardness according to DIN 53505 of 20 to 45 and comprises a foam layer, a cover layer and a lacquering layer in this order, wherein the foam layer has a density of 40 to 100 kg/m.sup.3 and a gel content of 20 to 80% and contains a polyolefin and the cover layer has a gel content of 0 to 20%, is thermoplastic and comprises at least two compact sublayers each comprising at least one thermoplastic selected from polyolefin and polyvinyl chloride.

Disclosed is a dispersible adhesively bonded wet tissue laminate and more particularly a dispersible wet wipe comprising two or more adhesively bonded tissue plies. Generally, the wipe comprises first, and second tissue plies adhesively bonded to one another by an adhesive, particularly a triggerable binder, disposed at the interface of the plies. The first and second tissue plies preferably comprise fibrous tissue plies and more preferably wet-laid tissue plies consisting essentially of conventional papermaking fibers. The adhesively bonded laminates are generally strong enough to withstand use, such as having a geometric mean wet tensile strength (GMWT) greater than about 250 g/in, but disperse quickly in water, such as having a Slosh Time less than about 60 minutes.

The present application relates to a laminating machine, including a first heating device, a first sheet material device, a second sheet material device, and a first combining device, the first combining device includes a heating mechanism and a rolling mechanism. A first sheet material, a first material strip, and a second sheet material are heated and pressed by the heating mechanism and the rolling mechanism, compared with a combination method of a PET film and an oven, it is not necessary to set arrange the PET film, cost of the PET film, arranging a PET film unwinding mechanism, and arranging a PET film winding mechanism is reduced, and occupied space is reduced, manufacturing cost is reduced, and there is no need to set up a longer oven, which improves combination efficiency and production efficiency, and further saves space and reduces device cost.

Apparatus and methods are described including an additional lens (24) made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens (24) is changed such as to conform with a curvature of abase eyeglasses lens (22), without causing a loss of the optical design of the additional lens (24), by heating the additional lens (24) to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (24). Subsequently, the additional lens (24) is adhered to the base eyeglasses lens (22). The optical design of the additional lens (24) is such that, upon being adhered to the base eyeglasses lens (22), the adhered base eyeglasses lens (22) and the additional lens (24) provide a combined lens (20) having a desired optical prescription. Other applications are also described.

Disclosed is a method for manufacturing a bonded body that includes a glass member, a bonding subject member, and a bonding portion bonded to the glass member and the bonding subject member. The method includes a setting step, a pressing step, and a bonding portion formation step. The setting step is a step of setting a jig main body lid on a jig main body in a state in which a stack is disposed in a recess of the jig main body. The pressing step is a step of adjusting an atmospheric pressure in the recess of the jig main body after the setting step to press the stack with the jig main body lid. The bonding portion formation step is a step of forming the bonding portion from a bonding material included in the stack in a state in which the stack is pressed in the pressing step.
