Abstract

This invention concerns a method and apparatus for simultaneously winding a plurality of filaments to form a mass transfer unit. A series of filaments axially spaced along a central core member are wound upon it as it is turned about a longitudinal axis to initially secure the spaced filaments thereto. Separator blocks are then placed in position one at a time while turning the core member to clamp the filaments between the separator blocks and the core member. The core member and separator blocks continue turning while additional separator blocks are added one at a time to form a plurality of radial stacks of separator blocks so that the filaments are clamped between adjacent separator blocks in each stack. Simultaneously the filaments are fed axially so that they are wound helically on the separator blocks. One aspect of the method is to insure proper action in withdrawing each filament from its supply coil without backlash or tangling; each coil is secured in a generally upright stationary position within a container, which is then filled with discrete rounded particles to a depth to surround and submerge the supply coil, and the filament is then pulled upward off the upper end of the supply coil. Apparatus particularly adapted for carrying out this method includes a pair of axially spaced supports mounted to turn on a common axis with radial guide channels on each support for receiving and supporting one end of each of the separator blocks to form plurality of radial stacks.

Claims

1. The method of withdrawing a filament from a helically wound supply coil comprising:

mounting the supply coil in a generally upright position below the level of a blanket of discrete smooth rounded particles surrounding the supply coil, to produce inward forces on the coil throughout its length preventing looseness of the coiled filament, and pulling the filament off one end of the supply coil.

2. The method set forth in claim 1 in which the particles comprise a natural agricultural seed product.

3. The method set forth in claim 1 in which the particles comprise milo maize.

4. The method of withdrawing a filament from a helically wound supply coil comprising:

mounting the supply coil in a generally upright stationary position within a container, filling the container with discrete smooth rounded particles to a depth to completely surround the supply coil, to produce inward forces on the coil throughout its length preventing looseness of the coiled filament, and pulling the filament upward off the upper end of the supply coil.

5. The method of withdrawing a filament from a helically wound supply coil comprising:

mounting the supply coil in a stationary position below the level of a blanket of discrete smooth rounded particles surrounding and submerging the supply coil, to produce inward forces on the coil throughout its length preventing looseness of the filament on the coil and pulling the filament through the blanket off one end of the supply coil.
