## Abstract

A cable spool for use in automated cable winding applications, said cable spool comprising a barrel having an outside diameter and a length, and two annular flanges located at opposite ends of said barrel, wherein each one of said flanges has an inward facing side directed towards said other flange and an outward facing side, each one of said flanges includes at least one through-hole extending between said inward facing side and said outward facing side, wherein each one of said through-holes forms a start hole, and each one of said flanges includes at least one reinforcement portion positioned between said barrel and said through-holes, wherein said at least one reinforcement portion has a height measured in a radial direction from a lateral surface of said barrel to a distal edge of said at least one reinforcement portion.

## Claims

### Claim 1

A cable spool for use in automated cable winding applications, said cable spool comprising:
a barrel having an outside diameter and a length, and
two annular flanges located at opposite ends of said barrel,
wherein each one of said flanges has an inward facing side directed towards said other flange and an outward facing side,
each one of said flanges comprises at least one through-hole extending between said inward facing side and said outward facing side, wherein each one of said through-holes forms a start hole, and
each one of said flanges comprises at least one reinforcement portion positioned between said barrel and said through-holes, wherein said at least one reinforcement portion has a height measured in a radial direction from a lateral surface of said barrel to a distal edge of said at least one reinforcement portion.

### Claim 2 (depends on 1)

A cable spool according to claim 1, wherein the height of said at least one reinforcement portion is approximately 5-15% of the outside diameter of said barrel.

### Claim 3 (depends on 1)

A cable spool according to claim 1, wherein the height of said at least one reinforcement portion is 3-7 mm.

### Claim 4 (depends on 1)

A cable spool according to claim 1, wherein the outside diameter of said barrel is 47-55 mm.

### Claim 5 (depends on 1)

A cable spool according to claim 1, wherein said cable spool is made of PE or PP having a density of 0.8-1.2 kg/m3.

### Claim 6 (depends on 1)

A cable spool according to claim 1, wherein said outward facing side of each one of said flanges is provided with a honeycomb shaped pattern of reinforcement ribs.

### Claim 7 (depends on 6)

A cable spool according to claim 6, wherein said honeycomb shaped pattern of reinforcement ribs is radially aligned around a longitudinal axis of said barrel.

### Claim 8 (depends on 7)

A cable spool according to claim 7, wherein said honeycomb shaped pattern of reinforcement ribs comprises reinforcement ribs having a draft angle of more than 1 degree.

### Claim 9 (depends on 1)

A cable spool according to claim 1, wherein an outward facing side of said at least one reinforcement portion is provided with a plurality of ribs extending in a radial direction.

### Claim 10 (depends on 1)

A cable spool according to claim 1, wherein said at least one reinforcement portion is an annular reinforcement portion.

### Claim 11 (depends on 1)

A cable spool according to claim 1, wherein said inward facing side of said flanges is substantially smooth.

### Claim 12 (depends on 1)

A cable spool according to claim 1, wherein each one of said through-holes is shaped as a rectangle with rounded corners.

### Claim 13 (depends on 12)

A cable spool according to claim 12, wherein each one of said through-holes has three straight edges and one concave edge, and said concave edge has a curvature
