Claims8
An apparatus for opening a tube of knit fabric comprising
- a) a slitter means for opening the knit tube;
- b) a conveying unit for said apparatus for moving the knit tube along a horizontal axis;
- c) a guide means on the fabric;
- d) sensing means associated with the slitter means to follow the guide means on the fabric so that the slitter means operates to cut the knit tube of fabric so that same is opened and laid flat;
- e) a conveyor device on the apparatus for moving the knit tube of fabric on a horizontal axis;
- f) means for opening the knit tube of fabric on said apparatus including an expandable member which operates to open the tubular knit fabric without appreciably tensioning and elongating the tubular knit fabric and prior to slitting same;
- g) said expandable member comprising a plurality of supports about an axially disposed member and said sensing means and slitter being part of said expandable member;
- h) means for said apparatus including a member for opening the fabric so that it is essentially free of wrinkles;
- and
- i) means for said apparatus including a device for maintaining the opened fabric in a flat state.

- a) a slitter means for opening the knit tube;
- b) a conveying unit for said apparatus for moving the knit tube along a horizontal axis;
- c) a guide means for the fabric;
- d) sensing means associated with the slitter means;
- said guide means on the knit fabric tube to serve as a guide for the sensing means to actuate the slitter means to cut the knit fabric tube whereby the fabric tube may be opened and laid flat so that the vertical wales form right angles with the courses of the knit fabric tube to approximate a woven fabric;
- e) a conveyor device on the apparatus for moving the knit tube of fabric on a horizontal axis;
- f) means for opening the knit tube of fabric on said apparatus including an expandable member which operates to open the tubular knit fabric with out appreciably tensioning and elongating the tubular knit fabric and prior to slitting same;
- g) said expandable member comprising a plurality of supports about an axially disposed member and said sensing means and slitter being a part of said expandable member;
- h) means for said apparatus including a member for opening the fabric so that it is essentially free of wrinkles;
- and
- i) means for said apparatus including a device for maintaining the opened fabric in a flat state.
