Abstract
A cutting member for cutting hard materials such as rock, concrete, etc., includes a support unit in the shape of a wire. The free ends of the wire are joined together to form an endless unit. Cutting elements are provided at regular distances from each other along the full length of the wire. Each cutting element is firmly connected to a cutting element carrier and supported on the wire and at least in the mounted condition is firmly connected to a rider for guidingly engaging a portion of a saw. Driver members are attached to the wire and the cutting element carriers are floatingly supported on the wire in functional engagement with the driver members.
Claims16
A cutting member for cutting hard materials said cutting member comprising:
- a wire having a length and free ends, the free ends being joined together to form an endless wire;
- a plurality of carriers disposed along the length of the wire;
- and
- a plurality of cutting elements connected to said carriers at regular distances from each other along the full length of the wire,
- said carriers being supported on the wire and at least in an assembled condition connected to a rider for guidingly engaging a portion of a saw,
- the cutting element carriers being floatingly supported on a wire and in a central area with regard to their axial extension along the wire are in functional engagement with driver members,
- said driver members being firmly connected to the wire at regular distances and wherein at least one of the cutting element carriers or riders has a stop arranged to engage one of the driver members on each side thereof for locking the cutting element in the longitudinal direction of the wire.
A method of forming a cutting member for cutting hard materials comprising the steps of:
- providing a support unit in a shape of a wire having a length and free ends joined together to form an endless wire;
- attaching at regular distances, along the length of the wire, cutting elements or groups of cutting elements;
- connecting each cutting element to a cutting element carrier that is supported on the wire and connecting said carriers to a rider;
- guidingly engaging said carriers to a portion of a saw;
- floatingly supporting the cutting element carriers on the wire and bringing the carriers into functional engagement with driver members within their axial extension along the wire;
- connecting driver members to the wire at regular intervals;
- and
- providing a stop for at least one of the cutting element carriers and the riders engaging the driver member at each side thereof for locking the cutting element in the longitudinal direction of the wire.
