Problems solved by technology

[0003] However, solvents are potentially toxic, requiring the use of a suction hood, which is expensive and complex to install and maintain
[0004] When solvents are used on the inner sole, even when the shoe is finished, some of the solvent will often remain in the inner sole and may cause the wearer foot pain or allergies to the sole
[0005] Known adhesive application methods also involve a large number of operations, many of which are done manually, while some operations, such as drying of solvents, take a long time to complete, thus reducing the output of the shoe manufacturing line

Embodiment Construction

[0036] Referring to the drawings, machine 10 is shown for applying adhesive layer 12 to first surface 24 of object 22 .

[0037] The term adhesive layer 12 refers to both a generally planar adhesive film having a constant and / or average thickness, and an adhesive layer having a varying and / or uneven thickness, eg, when applied by hand.

[0038] Object 22 may be generally flat, ie have a small thickness.

[0039] Alternatively, object 22 may be non-flat and thick, and / or have a complex shape, ie, may be a definite three-dimensional object.

[0040] In the example shown, the object 22 is the inner sole of a shoe or a so-called hygienic inner sole on which the adhesive layer 12 is applied to bond it inside the shoe. In the example shown, the insole has a maximum length of about 40 to 50 cm, and a maximum width of about 10 to 20 cm.

[0041] Whether manually or automatically loaded, the object 22 is positioned on a support surface 14 supported by a frame 34 (in the illustrated e...

Abstract

An assembly of tapes for applying an adhesive layer (12) to a first surface (24) of an object (22); the assembly comprising a first (30) and a second tape (32); the first tape (30) comprising a supporting layer (15) and an adhesive layer (12) supported by the supporting layer (15); the second tape (32) having at least a cover layer (16) adhering more firmly to the adhesive layer (12) than the supporting layer (15) to the adhesive layer (12).

Description

technical field [0001] The present invention relates to a machine and related method for applying an adhesive layer on the surface of an object such as an inner sole of a shoe, to obtain an object having at least one adhesive surface ready for bonding to another object, such as a shoe, and No trimming operation is required. Background technique [0002] On shoemaking machines, the inner sole is coated by spraying or brushing a liquid adhesive, that is, an adhesive dispersed or mixed in a liquid such as a solvent such as alcohol, ether, ketone, or hydrocarbon. A layer of adhesive is applied and bonded to the inside of the shoe. An adhesive is used, for example a polychloroprene solvent adhesive, which is brushed on the insole and the inside of the shoe. When the solvent evaporates, ie when the adhesive dries, the insole and the shoe are bonded to each other. [0003] However, solvents are potentially toxic, requiring the use of suction hoods, which are expensive and compli...
