摘要:
The invention relates to a transformer unit, particularly for sawing, wherein the transformer unit (M) comprises a first machine element (1), particularly a shaft, performing a continuous rotational movement during the use of the transformer unit, and a second machine element (2) performing a limited alternating rotational motion on a part of the transformer unit, particularly a wing torsion device driven by pressurized medium. The transforming unit (M) is arranged to be coupled to an arrangement to supply driving energy for the transformer unit (M), such as a hydraulic pump unit. The first and second machine element (1, 2) of the transformer unit are preferably coupled to a device performing the same work. The device is used for performing first and second partial work performances, wherein in connection with a flanged chain saw it is operated in such a way that the first machine element (1) is arranged to rotate the chain saw during the sawing performance, and the second machine element (2) is arranged to feed the flange for the chain saw, or the like, during the sawing performance and to return the flange for the saw chain to the initial position of sawing during the sawing performance.

The portable sawmill (10) is constructed on a frame (12) having a series of mechanisms for loading and manipulating a log thereon and removing boards cut from the log. Powered tines load a log onto a vertically adjustable log deck (22), the deck (22) including powered mechanisms for turning and securing the log in the desired orientation for cutting. Cuts are made by a horizontally traveling band saw. The saw has no vertical adjustment. Board thickness is determined by the height of the vertically adjustable log deck (22). Cut boards are removed by a board sweep that pushes the board laterally from the top of the log onto a tray. The saw travels along the tray to push the board longitudinally onto a suitable platform for transport. All of the above mechanisms are controlled hydraulically from a single operator station on the mill, thus freeing the operator from many manual tasks and increasing production
摘要:
A band saw machine, wherein a pair of guide posts (7L) and (7R) vertically guiding a vertically movable saw blade housing rotatably supporting a drive wheel (17) and a driven wheel (21) are installed between the drive wheel (17) and the driven wheel (21). The upper travel part (23U) of a band saw blade (23) is disposed on the rear side of the guide posts (7L) and (7R), and the lower travel part (23L) of the band saw blade (23U) is disposed on the front side of the guide posts (7L) and (7R). When the band saw machine is viewed from the side, a width between the intersections of the axes of the both wheels (17) and (21) with the centerline of the width of the wheels is approximately equal to a width between the guide posts (7L) and (7R).

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.

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 stack of folded and glued corrugated paperboard boxes is slit in unison with a thin cutting blade having a linear cutting edge disposed parallel to the plane of the boxes and moved through the stack in an angular direction to slit essentially one box at a time. The stack is squared before slitting to align the box edges, however, the force of the blade on the stack as it moves therethrough holds the receding stack together such that the cut halves of each box may part laterally as the blade passes therethrough to avoid any crushing of the corrugated paperboard media.
