Claims
- 1. In a method of padding and extracting a continuously advancing circular knit fabric tube having upper and lower layers by passage through a puddle of impregnating liquid contained within an upwardly open nip defined by a pair of opposed horizontally disposed squeeze rolls, the steps of spreading the advancing fabric tube to a predetermined width, then immediately directing said spread fabric tube onto one of said squeeze rolls for advance in a generally downward direction through said puddle into said nip, the said upper layer of said fabric tube being free from contact with either of said squeeze rolls until its passage through said nip, and expelling any entrapped air in said fabric tube through the said upper layer thereof during its advance over the said one of said squeeze rolls toward engagement with said nip as the result of directing said fabric tube into said puddle of impregnating liquid under controlled tension.
- 2. In a method of padding and extracting a continuously advancing circular knit fabric tube having upper and lower layers by passage through a puddle of impregnating liquid contained within an upwardly open nip defined by a pair of opposed horizontally disposed squeeze rolls, the steps of spreading the advancing fabric tube to a predetermined width, geometrically orienting the said upper and lower layers of said advancing fabric tube while said fabric tube is in its spread condition, then directing said spread and geometrically oriented fabric tube onto one of said squeeze rolls for advance in a generally downward direction through said puddle into said nip, and expelling any entrapped air in said fabric tube through the said upper layer thereof as the result of directing said fabric tube into said puddle of impregnating liquid under controlled tension by selectively varying the speed of advance of said upper and lower layers relative to the speed of advance through said nip.
