Abstract
A method of producing a thermoadhesive fabric covering includes applying in spots a dual coating of thermoadhesive polymers to a textile support which is then dried and cooled.
Claims18
A method for the production of thermoadhesive fabric coverings, in which a textile support receives a coating of thermoadhesive polymers distributed in spots upon the textile support, comprising the steps of:
- bonding the the textile support onto a conveyor belt;
- depositing a first layer of thermoadhesive polymers in spots upon the textile support by a first perforated rotary frame;
- depositing a second layer of thermoadhesive polymers in spots identical to that of the first layer and upon the first layer of thermoadhesive polymers by a second perforated rotary frame;
- separating the coated textile support from the conveyor belt;
- passing the coated textile support through a continuous drying furnace and;
- cooling said coated textile support.
A thermoadhesive fabric covering which comprises a textile support having a first and second surface and a thermoadhesive coating distributed in spots on said first and second surfaces wherein each spot of the coating comprises a first layer formed from polymers and a second layer formed from thermoadhesive polymers dissimilar to the polymers of the first layer, the first layer being arranged under the second layer.
