Protective sleeve with knitted opening and method on construction

1. A sleeve for protecting elongate members, comprising:

a tubular wall extending between opposite open ends, said tubular wall being constructed from a plurality of yarns interlinked with one another by a plurality of knit stitches, said wall having one side with a pair of opposite longitudinally extending edges and another side with a pair of opposite longitudinally extending edges with opposite pairs of edges being at least partially knit together; and

at least one opening integrally knit in said tubular wall between said opposite open ends, said opening extending longitudinally along said tubular wall and having a circumferentially continuous, knit outer periphery.

2. The sleeve of claim 1 wherein said tubular wall is circumferentially continuous and said at least one opening is formed between at least one of the pair of edges.

3. The sleeve of claim 1 wherein said circumferentially continuous, knit outer periphery is knit concurrently with said tubular wall from at least some of said plurality of yarns.

4. The sleeve of claim 3 wherein said circumferentially continuous, knit outer periphery is formed from uncut ones of said plurality of yarns.

5. The sleeve of claim 1 wherein each of said plurality of yarns extends continuously between said ends.

6. The sleeve of claim 1 wherein said ends are finish knit.

7. The sleeve of claim 1 wherein said tubular wall has a pattern of said knit stitches, said at least one opening being configured by a change in said pattern.

8. The sleeve of claim 1 wherein said tubular wall has a pair of said openings, one of said ends being reverse folded to provide said tubular wall with an inner wall and an outer wall, said inner wall having one of said pair of openings and said outer wall having the other of said pair of openings, said pair of openings being registered with one another to provide a single opening extending through said inner wall and said outer wall.

9. A method of constructing a tubular sleeve for protecting an elongate member, comprising:

providing a flat bed knitting machine;

knitting a tubular sleeve having one side with opposite longitudinally extending edges knit on one bed of the flat bed knitting machine and another side with opposite longitudinally extending edges knit on an opposite side of the flat bed knitting machine with opposite pairs of the longitudinally extending edges being at least partially knit together on the flat bed knitting machine with a knit pattern extending between opposite open ends on the machine; and

knitting at least one longitudinally extending opening between said opposite open ends while continuously knitting the tubular sleeve.

10. The method of claim 9 further including weft knitting the tubular sleeve.

11. The method of claim 9 further including knitting the tubular sleeve having a circumferentially seamless wall with said at least one opening extending between at least one of the pair of edges.

12. The method of claim 9 further including knitting a pair of the openings between the opposite ends and reverse folding one of the ends and registering the pair of opening with one another to form a single opening through an overlapped inner and outer layer of the sleeve.

13. The method of claim 9 further including finish knitting the opposite ends.

14. The method of claim 9 further including knitting the opening by changing the knit pattern on the knitting machine.

15. The method of claim 14 further including initiating at least one of the openings by forming a bind off knit pattern.
