Motorized flat web winder
View Patent ↗A motorized flat web winder has a revolving work holder and a source of drive for turning the revolving work holder. The revolving work holder presents a generally planar support surface. The source of drive turns the revolving work holder about a turning axis. The generally planar support surface cuts the turning axis more or less perpendicularly. The generally planar support surface has a spaced pair of keeper pins extending out from an affixed butt end to a spaced tip end. Preferably, the keeper pins are off-center relative the turning but orbit about the turning axis in a near orbit. More preferably still, the keeper pins orbit the turning axis by a measure which makes either of the brass coupling ends of a fire hose the center of a spiral coil formed therefrom.
1. A motorized flat web winder, comprising:
a revolving work holder presenting a support surface;
a drive shaft affixed to and turning the revolving work holder about a turning axis;
a source of drive for the drive shaft; and
a spaced pair of keeper pins extending out of the support surface from an affixed butt end to a spaced tip end, at least one of which pins is off-center relative the turning axis of the revolving work holder;
wherein the support surface is shallowly concave.
2. The motorized flat web winder of claim 1 , wherein:
both keeper pins are off-center but in a near orbit about the turning axis of the revolving work holder.
3. The motorized flat web winder of claim 2 , wherein:
the keeper pins are tapered such that the butt end is wider and the tip end is narrower.
4. The motorized flat web winder of claim 1 , wherein:
the keeper pins are tapered such that the butt end is wider and the tip end is narrower.
5. The motorized flat web winder of claim 4 wherein:
the support surface cuts the turning axis perpendicularly; and
the revolving work holder is disposed such the turning axis is oriented at about 15° to horizontal such that the plane of the support surface is tilted to about 75° to horizontal.
6. The motorized flat web winder of claim 5 , wherein:
the tilt of the support surface is adjustable to include vertical.
