Abstract
Abstract A multi-layer adhesive material for producing an adhesive bond between two essentially mutually parallel surfaces, especially for providing an adhesive bond between a surface of a ski and a surface of an attachment body for the ski, wherein the multi-layer adhesive material contains two outer adhesive surfaces and at least one predominantly elastic carrier layer. There is provided in addition to the predominantly elastic carrier layer at least one predominantly plastic carrier layer having at its outwardly directed side or face one of the two adhesive surfaces of the adhesive material. The method of using such adhesive material for establishing an adhesive connection between the aforementioned surfaces contemplates profiling the surface of the body to be connected with another body for increasing its adhesive surface, and which profiled surface faces the predominantly plastic carrier layer of the adhesive material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
45 words
A multi-layer composite for producing an adhesive bond between two substantially mutually parallel surfaces comprising two outer adhesive layers, one on each opposed major face, a plastic carrier layer immediately adjacent one outer adhesive layer and an elastic carrier layer adjacent the plastic carrier layer.
Claim 2
Dependent Claim
45 words
A multi-layer composite for producing an adhesive bond between two substantially mutually parallel surfaces comprising two outer adhesive layers, one on each opposed major face, a plastic carrier layer immediately adjacent one outer adhesive layer and an elastic carrier layer adjacent the plastic carrier layer.
Claim 3
Dependent Claim
23 words
The multi-layer composite of claim 1 wherein a second plastic carrier layer is disposed immediately adjacent the second outer adhesive layer interior thereto.
Claim 4
Dependent Claim
23 words
The composite as defined in claims 1 or 2, wherein: the total thickness of the composite amounts to about 0.2 to 1 mm.
Claim 5
Dependent Claim
31 words
The composite as defined in claims 1 and 2, wherein: the thickness of the predominantly plastic carrier layer amounts to about 40% to 60% of the total thickness of the composite.
Claim 6
Dependent Claim
22 words
The composite as defined in claim 2, wherein: the elastic carrier layer is sandwiched between and heat-sealed to the plastic carrier layers.
Claim 7
Dependent Claim
96 words
A method of bonding a first body to a second body by means of an adhesive material, comprising the steps of: profiling a surface of the first body which is to be connected with the second body in order to increase its adhering surface; pressing said surface of the first body against an adhesive surface of the composite of claim 1 or claim 2 and bonding the surfaces together; and pressing a surface of a second body against the other adhesive surface of the composite of claim 1 or claim 2 and bonding the surfaces together.
Claim 8
Dependent Claim
21 words
The method as defined in claim 6, wherein: profiling of the adhering surface of the first body is accomplished by stamping.
Claim 9
Dependent Claim
21 words
The method as defined in claim 6, wherein: profiling of the adhering surface of the first body is accomplished by milling.
Claim 10
Dependent Claim
54 words
The method as defined in claim 6, wherein: said adhesive bonding is produced at a temperature greater than the temperature expected during loading of the adhesive bonds when said first body is in use, so that the adhesive layers are more easily plastically deformable during production of the adhesive bonds than after subsequent cooling.
