The present invention includes a chain type cutting apparatus for continuous cutting of a rope of a center-filled consumable product into individual pieces, which includes a first continuous elongate rotary chain with a plurality of first open die cavity portions and a second continuous elongate rotary chain with a plurality of second open die cavity portions. The first and second die cavity portions are mutually engageable to form a closed die cavity about a rope of center filled consumable product, forming pieces. The invention incorporates four main variables, dwell time, chain length, chain speed and the number of closed die cavities in simultaneous engagement. These four variables can be altered to increase the output of the product, as well as maintain a satisfactory seal of the center-filled consumable product.

A multi-bandsaw machine includes several bandsaws, for cutting a material into a plurality of plates in a single process. At least one side edge of each bandsaw has a plurality of diamond grits, and the bandsaws rotate in a single direction on the multi-bandsaw machine, so as to cut the material with the diamond grits and form a cutting notch on the material. The cutting notch has a depth to kerf ratio at least larger than 100:1 during the process of cutting the material with the diamond grits in each hour.

A sawmill for milling a length of sawbolt includes a frame and a plurality of saws movably mounted to the frame. The plurality of saws include bandsaws, edging saws, and chain saws for making various cuts necessary in the milling process. A saw positioning system is coupled to the plurality of saws for positioning the saws relative to the frame. A controller is coupled to the saw positioning system. The controller provides a saw position signal and the saw positioning system positions the saws in response to the saw position signal. A number of log positioning mechanisms are also provided.

In a bandmill having a column and a pair of arbor-supported wheels carrying and driving an endless saw, a mechanism is provided to move the first wheel relative to the second wheel to accommodate fluctuations resulting from saw loading conditions; the mechanism comprises: a vertical post having one end slidably received in the column; a horizontal plate fixed to the other end of the post; a arbor support fixedly mounted to the plate and having a hinge portion; a tension arm having a first portion attached to the arbor and a second portion extending lengthwise over the plate; and resilient elements located between the second portion of the tension arm and the plate. The arbor of the first wheel includes a central section to which the first wheel is mounted for rotation about a first axis and an end section hingedly connected to the hinge portion of the arbor support along a second axis which is eccentric relative to the first axis; the end section has a recess so shaped as to receive the hinge portion therein and to allow pivotal movement of the arbor about the eccentric axis.

TIONED RELATIVE TO LINE BAR SO THAT OVERHANG LENGTH FOR CANT OF MINIMUM WIDTH IS LESS THAN OVERHANG LENGTH FOR CANT OF MAXIMUM WIDTH PROVIDING IMPROVED SUPPORT TO REDUCE CHATTER WHEN CUTTING NARROW CANTS.
CROWDER ROLL ASSEMBLY FOR USE WITH INFEED CONVEYOR AND FIXED LINE BAR OF SETTING BANDMILL. THE CHANGE SAW CANT WIDTH, BANDMILL SETS TO LINE BAR WHICH REMAINS STATIONARY. BANDMILL CUTS CANT FED THROUGH SAW, SAWN DATUM FACE OF CANT BEING PRESSED AGAINST LINE BAR BY CROWDER ROLL TO MAINTAIN AXIAL FEED PARALLEL TO LINE BAR. CONTACT STRIP BETWEEN ROLL AND CANT IS LONGITUDINALLY SEPARATED FROM SAW BY OVERHANG LENGTH. ROLL IS JOURNALLED ON ARM HINGED AT ONE END TO PERMIT ROTATION OF ARM TO ACCOMMODATE CANTS OF DIFFERENT WIDTHS. HINGE AXIS POSI-
摘要:
Saw mill apparatus including a plurality of bandsaws cooperatively adjustable relative to each other transversely of the apparatus for cutting successive boards of predetermined thickness from a log firmly supported in its passage through the apparatus. The log is progressively fed to the bandsaws running in the same direction for successive operations to thus utilize the full workload capacity of the apparatus for constant work fed to it.
