    Abstract: A band saw machine includes a machine frame unit with a longitudinal guideway, a cam follower movable along the guideway, a wheel mount movable with the cam follower between closer and remote positions relative to a first wheel mounted on the machine frame unit, a biasing member disposed to bias the wheel mount to the remote position, a second wheel mounted on the wheel mount, a band saw blade trained on the wheels, and an actuating shaft with a cam end which engages the cam follower. The wheel mount can be kept in the closer position with a friction force that counteracts the biasing force of the biasing member by turning the actuating shaft so as to permit replacement of the band saw blade.

  • Publication number: 20100212465
    Abstract: The cutting machine comprises a horizontal knife (17) for cutting a block (40) into plates (41). To allow for removal of a stack of plates (42) before the whole block (40) has been cut, a removal means comprising a removal conveyor (32) is provided. After completion of the last cut, the knife (17), after reversal of its cutting edge, will be entered into the cutting gap (43) again and be lifted, thus allowing a separating member (34) of the removal conveyor (32) to enter the resultant gap (44). By driving the conveyer belt (12), the stack of plates (42) is transferred onto the removal conveyor (32).

  • Publication number: 20100186564
    Abstract: A device for cutting a length of pipe includes a clamp portion for clamping around a length of pipe and a bow moveable with respect to the clamp portion that retains a loop of diamond embedded wire. The device further includes a feed for driving the bow with respect to the clamp portion and a detector for detecting bending of the wire and a control responsive to the detector for controlling feed rates. The device is made of modular parts and has synchronizing arms for clamping around a length of pipe. In one embodiment, the wheels are retained in enclosures with slots through which the cutting wire passes.

  • Patent number: 7654184
    Abstract: In a band saw machine in which a pair of guide posts for guiding a saw blade housing that rotatably supports a driving wheel and a driven wheel and can vertically move in the vertical direction are provided between the driving wheel and the driven wheel, an upper traveling part of a band saw blade is disposed in the rear of the guide posts and a lower traveling part of a band saw blade is disposed in front of the guide posts, when the band saw machine is viewed from the side, an intersection point between centers of the both wheels and the center line of the wheel width is almost equal to the width of the guide posts.

  • Publication number: 20090314147
    Abstract: Machine for cutting paper logs, comprising means for supporting one or more logs (3) disposed side by side, means for advancing the logs (3) on said support means, means for the transverse cutting of the logs (3) and means for blocking logs (3) during their cutting. The said cutting means comprise an annular band blade (4) having a bevel (400, 401) on both its edges, provided in correspondence to a cutting station (T) in which the logs (3) are cut and connected to corresponding guiding and actuating means, the said blade (4) featuring a portion (40) defining a corresponding cutting plane which is oriented orthogonally with respect to the longitudinal axes of logs (3), the said blade being provided with a sharpening device (100) continuously acting on both its bevels (400,401). The machine comprises means for the relative motion of logs (3) with respect to said blade (4) along the said cutting plane. The blade (4) acts on one log (3) at a time.
