Abstract
Abstract The device for gluing sheet-like textile articles contains a spreading station (15), a heating station (16), a pressing station (17) and a take-off station (18). The plate-shaped heating zones consist of several hollow-profile heaters (25) which are arranged next to one another and on the rear contact side (28) of which panel heaters are attached, each panel heater having at least one electrically heatable heating device (heating wire). The heating wires can be controlled each individually or in groups.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
163 words
A device for gluing sheet-like textile articles comprising, two conveyor belts which are driven continuously and at the same speed, said conveyor belts overlaying each other in a transport region, with textile articles to be joined together being conveyable between the overlaying belts in the transport region, a heating station having several heating zones, and a pressing station located downstream of the heating zones in the conveying direction, the pressing station and individual heating zones being arranged in succession in the transport plane of the conveyor belts, each heating zone having a heatable plate (23, 24), wherein each of the heatable plates (23, 24) consists of several hollow-profile heaters (25) arranged next to one another, and wherein each hollow-profile heater includes an electrically heatable panel heater (26) attached to the rear side of a top wall (28) of its respective hollow-profile heater said device for gluing further including means for selectively supplying electricity to said panel heaters (26) either individually or in groups.
Claim 2
Independent Claim
163 words
A device for gluing sheet-like textile articles comprising, two conveyor belts which are driven continuously and at the same speed, said conveyor belts overlaying each other in a transport region, with textile articles to be joined together being conveyable between the overlaying belts in the transport region, a heating station having several heating zones, and a pressing station located downstream of the heating zones in the conveying direction, the pressing station and individual heating zones being arranged in succession in the transport plane of the conveyor belts, each heating zone having a heatable plate (23, 24), wherein each of the heatable plates (23, 24) consists of several hollow-profile heaters (25) arranged next to one another, and wherein each hollow-profile heater includes an electrically heatable panel heater (26) attached to the rear side of a top wall (28) of its respective hollow-profile heater said device for gluing further including means for selectively supplying electricity to said panel heaters (26) either individually or in groups.
Claim 3
Dependent Claim
29 words
