Abstract

Devices having shafts may require that one part be solid and the other flexible. An example is a copier auger which requires a solid shaft at one end which is open to collect toner, and a flexible shaft to allow routing of the auger through the machine. Here, a continuous, sectioned solid and flexible core is assembled, around which is molded an auger.

Continuous Solid and Flexible Shaft Device

Devices having shafts may require that one part be solid and the other flexible. An example is a copier auger which requires a solid shaft at one end which is open to collect toner, and a flexible shaft to allow routing of the auger through the machine. Here, a continuous, sectioned solid and flexible core is assembled, around which is molded an auger.

In the figure, a flexible shaft 10 made of wound wire is swaged to a solid shaft
11. The resultant core is placed in a mold, and an auger 12 molded thereon. This results in a common, continuous auger, avoiding discontinuities at points where two separately molded sections are joined.
