Abstract
Abstract A continuously operating apparatus for advancing a web by adhesively securing the same to a transport band such as a conveyor belt, coated on one side with a layer of thermoplastic adhesive which includes a pair of guide roll means over which such a transport band is trained with the layer of adhesive exposed, means for feeding a textile web onto said transport band, a heating roll means for heating said layer of adhesive, means for applying a contact pressure between said band and textile web to bond the band and web to one another as the web passes said heating roll means and means for controlling the contact pressure between the textile web and the transport band as a function of the speed of movement of said textile web past said heating roll means in order to achieve a substantially uniform adhesive force between said web and said layer of adhesive on said transport band.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
163 words
A continuously operating apparatus for advancing a web by adhesively securing the same to a transport band coated on one side with a layer of thermoplastic adhesive, comprising a transport band coated on one side with a layer of such thermoplastic adhesive, a pair of band-guide rollers over which said transport band is trained, means for feeding a textile web onto said transport band, heating roll means for heating said layer of thermoplastic adhesive, means for applying a contact pressure between said transport band and the textile web to bond said transport band and said textile web to one another as the web passes said heating roll means, and means for controlling the contact pressure between the textile web and the transport band as a function of the speed of movement of said textile web past said heating roll means in order to achieve a substantially uniform adhesive force between said textile web and said layer of thermoplastic adhesive on said transport band.
Claim 2
Dependent Claim
163 words
A continuously operating apparatus for advancing a web by adhesively securing the same to a transport band coated on one side with a layer of thermoplastic adhesive, comprising a transport band coated on one side with a layer of such thermoplastic adhesive, a pair of band-guide rollers over which said transport band is trained, means for feeding a textile web onto said transport band, heating roll means for heating said layer of thermoplastic adhesive, means for applying a contact pressure between said transport band and the textile web to bond said transport band and said textile web to one another as the web passes said heating roll means, and means for controlling the contact pressure between the textile web and the transport band as a function of the speed of movement of said textile web past said heating roll means in order to achieve a substantially uniform adhesive force between said textile web and said layer of thermoplastic adhesive on said transport band.
Claim 3
Dependent Claim
52 words
Continuously operating apparatus as defined in claim 1, wherein said means for applying a contact pressure between said transport band and said textile web comprises said heating roll means and one of said band-guide rollers, and a traveling carriage in which said heating roll means and said one band-guide roller are mounted.
Claim 4
Dependent Claim
30 words
Continuously operating apparatus as defined in claim 2, wherein said heating roll means is displaceably supported on said travelling carriage for movement selectively towards and away from said transport band.
Claim 5
Dependent Claim
50 words
Continuously operating apparatus as defined in claim 1, wherein said means for applying a contact pressure between said transport band and said textile web comprises said heating roll means and a cooperating pressure roll and a travelling carriage in which said heating roll means and said pressure roll are mounted.
Claim 6
Dependent Claim
15 words
Continuously operating apparatus as defined in claim 4, and said band-guide rollers beinG stationarily mounted.
Claim 7
Dependent Claim
47 words
Continuously operating apparatus as defined in claim 1, wherein said means for applying a contact pressure between said transport band and said textile web comprises said heating roll means and a cooperating pressure roll and both said heating roll means and said pressure roll being stationarily mounted.
Claim 8
Dependent Claim
21 words
Continuously operating apparatus as defined in claim 6, and further including a travelling carriage means for displaceably supporting said band-guide rollers.
Claim 9
Dependent Claim
65 words
Continuously operating thermoplastic apparatus as defined in claim 1, said controlling means for said contact pressure comprising hydraulic means for regulating the contact pressure and said hydraulic means incorporating a pressure cylinder and a control pump driven synchronously with respect to said heating roll for generating a hydraulic pressure in said pressure cylinder as a function of the rotational speed of said heating roll means.
Claim 10
Dependent Claim
41 words
Continuously operating apparatus as defined in claim 1, said controlling means for said contact pressure including a pressure cylinder, mechanical feeler means and a pressure regulating valve actuated by said mechanical feeler means for controlling the pressure within said pressure cylinder.
Claim 11
Dependent Claim
63 words
Continuously operating apparatus as defined in claim 9, further including a travelling carriage on which said heating roll is mounted, a fluid motor for driving said travelling carriage, a regulating valve for controlling the rotational speed of said fluid motor and said mechanical feeler means including at least one feeler responsive to the movement of said travelling carriage for controlling said regulating valve.
Claim 12
Dependent Claim
116 words
Adhesive apparatus, particularly for printing purposes, comprising a transport band coated on one side with a layer of adhesive, means for feeding a textile web to be printed onto said transport band, heating roll means for heating said layer of adhesive, means for applying a contact pressure between said transport band and the textile web to bond said transport band and said textile web to one another, and means for controlling the contact pressure between the textile web and the transport band as a function of the speed of movement of said textile web in order to achieve a substantially uniform adhesive force between said textile web and said layer of adhesive on said transport band.
