- 1. A method for producing biodegradable absorbent pads comprising the steps of:
- moving a rope of biodegradable absorbent material in one direction through the inside of a hollow tube;
- providing a web of non-woven rayon fibers as a biodegradable material;
- moving the web of biodegradable material, having elongated edges, along the outside of said hollow tube in a direction which is opposite to the direction of movement of said rope; forming said web into a hollow cylinder; non-heat sealing said edges of said web together; reversing the direction of said web approximately 180.degree. ; moving said web in said reversed direction through the inside of said hollow cylinder between said rope of absorbent material and the inside walls of said hollow cylinder; covering said rope of absorbent material with said web.
- 2. A method as set forth in claim 1, further including the step of moving the adjacent sealed edges of said web to the inside of said cylinder formed by said web.
- 3. A method as set forth in claim 2, further including the steps of expelling a strand formed by the combination of said absorbent material and said web out of said tube in the same direction as the movement of said rope and said web after reversal of the movement of said web; forming adjacent panels in said strand; and cutting said strand into pads having predetermined lengths.
