Abstract
A bandmill has a frame, first and second bandwheels for receiving and guiding a bandsaw, the bandwheels being rotatable about spaced-apart, generally parallel axes of rotation, first and second arbors of the first and second bandwheels respectively, apparatus fixedly mounting the first arbor on the frame, and a strain mechanism for the bandsaw. The strain mechanism comprises a bearing member for the second arbor and an elastomeric member compressibly supporting the bearing member.
Claims16
A bandmill having a frame, first and second bandwheels for receiving and guiding a bandsaw, the bandwheels being rotatably about spaced-apart, generally parallel axes of rotation, first and second arbors for the first and second bandwheels respectively, means mounting the first arbor on the frame against movement towards and away from the second arbor, means mounting the second arbor on the frame for limited movement towards and away from the first arbor, and a strain mechanism for the bandsaw comprising a bearing member including a carrier arm for the second arbor and a resilient strain source comprising solely an elastomeric member compressibly received between the carrier arm and the frame and having sufficient rigidity to support the carrier arm and any load applied thereto during operation of the bandmill.
