Abstract
Systems and methods for cutting grass and other materials using a disk-shaped cutting web are disclosed. The cutting web has a center portion that is attachable to a rotating shaft adapter. The center portion may be a solid annular disk having a keyed aperture that allows it to be mounted on a spindle of a rotating shaft adapter. The cutting web has multiple strings that are connected to the center portion and extend outward from it in a generally radial direction (away from the center of the disk). The strings intersect with each other to form junctions at which they are joined, thereby forming a web that can be rotated at high speed to perform a cutting function. The strings of the web can have sharp or serrated edges and may be colored to increase the visibility of the web.
Claims16
A product comprising:
- an annular disk-shaped cutting web;
- wherein the cutting web has a center portion that is attachable to a rotating shaft adapter;
- wherein the cutting web has a plurality of cutting strings which are connected to the center portion and extend radially outward from the center portion;
- wherein the plurality of cutting strings intersect with each other at a plurality of junctions and are joined with each other at the junctions, thereby forming the disk-shaped cutting web;
- wherein when the disk-shaped cutting web is rotated, an outer portion of the plurality of cutting strings at a periphery of the disk-shaped cutting web perform a cutting function;
- wherein when one of the junctions breaks, one or more of the plurality of strings that intersected at the unbroken junction form new cutting elements of the cutting web;
- wherein the outer portion of the plurality of strings at the periphery of the disk-shaped cutting web comprise a plurality of arms, wherein each arm includes a plurality of the strings that are attached to the center portion at different points and that are joined together at a junction near the periphery of the cutting web.
An apparatus comprising:
- a motor;
- a rotating shaft coupled to the motor, wherein the motor drives the rotating shaft;
- a shaft adapter coupled to the rotating shaft, wherein the rotating shaft drives the shaft adapter;
- and
- an annular disk-shaped cutting web removably attached to the shaft adapter;
- wherein the cutting web has a center portion that is attached to the shaft adapter, and has a plurality of strings which are connected to the center portion and extend radially outward from the center portion, wherein the plurality of strings intersect with each other at a plurality of junctions and are joined with each other at the junctions, thereby forming the disk-shaped cutting web;
- wherein when the shaft adapter and the disk-shaped cutting web are rotated by the motor, an outer portion of the plurality of strings at a periphery of the disk-shaped cutting web perform a cutting function;
- wherein when one of the junctions breaks, a plurality of strings that intersected at the unbroken junction form cutting elements of the cutting web;
- wherein the outer portion of the plurality of strings at the periphery of the disk-shaped cutting web comprise a plurality of arms, wherein each arm includes a plurality of the strings that are attached to the center portion at different points and that are joined together at a junction near the periphery of the cutting web.
