Abstract
A Coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material (e.g. a roll or a Leporello-stack) of paper, can include a reel having at least two deflectors, and having a rotational axis extending in vertical direction. The deflectors can be a mandrel, hook, deflector edge, or the like.

A coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material, comprising:
- a reel having a rotational axis extending in a vertical direction, and at least two deflectors arranged with respect to the rotational axis and configured to roll-up the three-dimensional cushioning material;
- and
- a housing surrounding the reel fully circumferentially in a radial direction and on both sides in an axial direction of the rotational axis in a closed state.
A coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material, comprising:
- a reel having a rotational axis extending in an axial direction, and at least two deflectors arranged with respect to the rotational axis and configured to roll-up the three-dimensional cushioning material around the at least two deflectors to form a cushion around the at least two deflectors;
- and
- a drive configured to drive the reel to roll-up the three-dimensional cushioning material around the at least two deflectors.
A coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material, comprising:
- a reel having a rotational axis extending in an axial direction, and at least two deflectors arranged with respect to the rotational axis and configured to roll-up the three-dimensional cushioning material around the at least two deflectors to form a noncircular-shaped and planar curved-shaped cushioning spiral around the at least two deflectors.
