Abstract
Abstract A method of manufacturing a backed tufted carpet consisting of cylindrical tufts of pile yarn inserted in a backing fabric, includes the steps of coating the fixing (short) ends of the tufts with an adhesive, producing a backing - less sheet of foamed rubber, and sticking the sheet on the backing fabric. The adhesive may be caused to fill any gaps between the tuft ends thus improving the resilience of the carpet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A method of manufacturing a tufted carpet comprising the steps of traversing a backing fabric which has a front and a back past a row of tufting needles, causing said needles to insert straight tufts of pile yarn through said backing fabric with each tuft having a relatively long, pile end projecting forwardly from the front of the backing fabric and an opposed relatively short fixing end projecting from the back of the fabric, applying an adhesive to said short ends of said tufts at the back of the fabric to secure them in said fabric, separately producing a layer of resilient foamed rubber, sticking said layer to said back of said backing fabric and said short ends of said tufts by means of an adhesive, and splaying said short ends apart and situating them in flattened condition against the back of the fabric, said splaying and flattening of said short ends being carried out at a time no later than the sticking of said layer to said back of said backing fabric.
Claim 2
Independent Claim
173 words
A method of manufacturing a tufted carpet comprising the steps of traversing a backing fabric which has a front and a back past a row of tufting needles, causing said needles to insert straight tufts of pile yarn through said backing fabric with each tuft having a relatively long, pile end projecting forwardly from the front of the backing fabric and an opposed relatively short fixing end projecting from the back of the fabric, applying an adhesive to said short ends of said tufts at the back of the fabric to secure them in said fabric, separately producing a layer of resilient foamed rubber, sticking said layer to said back of said backing fabric and said short ends of said tufts by means of an adhesive, and splaying said short ends apart and situating them in flattened condition against the back of the fabric, said splaying and flattening of said short ends being carried out at a time no later than the sticking of said layer to said back of said backing fabric.
Claim 3
Dependent Claim
30 words
A method as recited in claim 1 wherein all said steps with the single exception of the production of said resilient foamed layer, are performed sequentially in a single machine.
Claim 4
Dependent Claim
76 words
A method as recited in claim 1 in which the insertion of said tufts and the application of a first layer of adhesive are effected on one machine, whereafter the part-finished carpet is transferred to another machine where said part - finished carpet receives a second coating of adhesive on the first, said second coating filling any gaps between said short ends of said tufts, said foamed layer being applied to said second layer of adhesive.
Claim 5
Dependent Claim
16 words
A method as recited in claim 1 including the step of setting said adhesive by radiation.
Claim 6
Dependent Claim
16 words
A method as recited in claim 1 wherein said backing fabric is selected from non-woven material.
Claim 7
Dependent Claim
45 words
In a method as recited in claim 1 and wherein the splaying apart of said short ends of said tufts is carried out at least partly by the application of said adhesive to said short ends of said tufts at the back of the fabric.
Claim 8
Dependent Claim
38 words
In a method as recited in claim 6 and wherein the splaying apart and flattening of said short ends of said tufts is completed simultaneously with the sticking of said layer to said back of said backing fabric.
Claim 9
Dependent Claim
39 words
In a method as recited in claim 7 and wherein the sticking of said layer to said back of said fabric is brought about by passing said layer and said backing fabric together with said tufts between nip rollers.
