This invention relates to a saw mill for sawing logs, comprising a base on which there is arranged a stationary means for reception of a log, a saw device provided with an endless band saw blade, which device is carried by a means that is arranged on the base and is movable in relation to this one in a direction which is essentially parallel with the longitudinal direction for the imaginary log, the band saw blade having two essentially horizontal portions which during sawing have a motion direction that is essentially perpendicular to the intended motion direction of the means carrying the saw device. According to the invention the means carrying the band saw device (1) comprises a sledge (2) or the like, positioned in the saw mill on one side of the stationary means (24) for reception of the log. Furthermore, the sledge is slidable on at least two elongated, essentially parallel prisms (8, 9), which function as a guide and dolly means for the sledge with the band saw device, and which has a longitudinal direction that is essentially parallel with the longitudinal direction of the imaginary log.

Apparatus for shaping wood comprises a carriage (2) having a front pair of wheels (3) and a rear pair of wheels (4), the carriage mounting a saw blade (1 ) and a saw motor for driving the saw blade to perform a sawing action trans- versely of the carriage. The front pair of wheels (3) is arranged to run on a first pair of guide rails (5) and the rear pair of wheels (4) is arranged to run on a second set of guide rails (6) extending parallel to the first set of guide rails. A bed for receiving the wood to be cut is located between the rails. The first and second guide rails (5 and 6) are formed with a vertically varying profile whose shape is determined by the cut shape of the wood it is desired to achieve, the profiles of the first set of guide rails being displaced horizontally with respect to the profiles of the second set of guide rails by a distance corresponding to the distance between the axes of rotation of the front and rear wheels. Drive means are provided to propel the carriage along the rails to follow the vertically varying profile.

A saw mill includes a base frame having a front and a rear and being sized and configured to support a log; saw apparatus having a cutting blade and being connected with the base frame for horizontal movement in a cutting stroke from a start position near the front of the base frame to an end position near the rear of the base frame and in a return stroke back to the front of the base frame and being for cutting in a generally horizontal plane a board from the log; power apparatus for powering the saw apparatus; at least one pushback arm connected to the saw apparatus and being sized and configured to engage and eject the board from atop the log during the return stroke; and, a board guide apparatus extending generally forwardly from the saw apparatus and including a crossbar and plurality of fingers connected with the crossbar and positioned to engage and guide the board in a desired path as it is being ejected from the log, each finger including an upper link connected to the crossbar and a lower link hingedly connected with the upper link.
摘要:
A band saw apparatus (10) having a pair of cutting units (12, 14). Each cutting unit (12, 14) has a frame (16) supporting a pair of wheels (18, 20). An endless saw blade (22) is arranged around each pair of wheels (18, 20). A frame (24) supports the cutting units (12, 14) so that the cutting units (12, 14) can travel toward one another along the frame (24). Alignment mechanisms (26) are provided for aligning the cutting units (12, 14) for relative angular displacement about a horizontal axis and for relative horizontal/lateral displacement. A cutting zone (38) is defined between the cutting units (12, 14) which is arranged to receive an item (40) to be cut. The cutting units (12, 14) are alignable in a cutting plane by the alignment mechanisms (26) such that when the cutting units (12, 14) move toward one another, the item (40) in the cutting zone (38) is cut by the saw blades (22).

The present invention is directed to a horizontal band saw machine capable of efficiently severing H-beams without a trouble of saw blade's pinching in the kerf. In the horizontal band saw machine, a saw blade (21) can sever one of flanges 20a that has been cut first in an H-beam (20), completely from top to bottom, prior to approaching the center of a web 20b and its vicinity.
摘要:
Apparatus for longitudinally segmenting a cruciform shaped irradiated boiling water reactor control rod having four elongated blades radially extending from a central spline, into four flat panels. The apparatus employs a double bladed band saw with the band saw blades orthogonally oriented at two different elevations and having one side of each band saw blade crossing over the center of the spline of the control rod in between the control rod blades.
摘要:
A stone slicer of slicing rough stone into stone plates having a predetermined thickness, which can improve productivity by reducing consumption of the rough stone by minimizing the thickness of a cut portion cut by a saw blade, and can reduce the treatment cost of sludge generated when the stone is sliced and prevent pollution due to the generated sludge. The stone slicer includes a base (10) on which stone is placed, four columns (22, 24, 26, 28) vertically installed at four edges of the base (10), a pair of a pair of platforms (30, 30’) installed left and right so as to be capable of simultaneously elevating along either side of the columns (22, 24, 26, 28), platform driving means (40, 40’) for elevating the platforms (30, 30’), one or more endless track type belt saws (70) each having opposite ends mounted in parallel with driving pulleys (50) and driven pulleys (60) provided at the platforms (30, 30’), and belt saw driving means (80) for driving the belt saws (70) to slice the stone placed on the base (10) to a predetermined thickness while rotating along an endless track by rotating the driving pulleys (50).
摘要:
A coping saw (10) is provided having two spaced-apart rotary actuators (50, 66) supported by a frame (12). Two sawblade sections (28, 30) extend between the rotary actuators (50, 66) and are intended to singularly engage a work piece. The saw is adapted to contain a drive mechanism (40) which is coupled to a first of the two rotary actuators (50) for moving the blade. At least one guide roller assembly (70A, 70B, 72A, 72B) is disposed adjacent each of the saw blade sections for providing stability and retaining said two saw blade sections between said two rotary actuators.
