A method of billing shingles cuttings with an apparatus for batch cutting shingle sheets and a method of cutting bundles of sheaves is also provided.

Abstract: A sheet cutting table 13, after sticking an adhesive sheet S to a semiconductor wafer W, for cutting the area outside the semiconductor wafer W as an unnecessary adhesive sheet S1 with a cutting device 15. The table 13 includes an inner table 52 which supports the semiconductor wafer W, and an outer table 51 corresponding to the unnecessary adhesive sheet S1 outside the semiconductor wafer W. The upper surface of the outer table 51 is provided with a non-adherable treatment surface 51A, and an adherable member formed with a ring member 53 or a plate member 63 for sticking the adhesive sheet S thereto.

Abstract: An improved sliding saw includes a base, a rotatable table rotatably disposed within the base, a first rail fixedly attached at least partially underneath and extending forwardly from the table, and a saw unit slidably disposed on the first rail, wherein a user moves the saw unit along the first rail towards the table to perform a cutting operation. A second embodiment of the saw includes a table having a top surface, the top surface having a first plane, a fence attached to the table, the fence having a front surface extending along a plane substantially perpendicular to the first plane, a first rail fixedly attached at least partially underneath and extending forwardly from the table along a first direction, and a saw unit slidably disposed on the first rail, wherein a user moves the saw unit along the first direction towards the table to perform a cutting operation. Preferably, the fence is rotatably attached to the table.

Abstract: A circular saw includes a universal arm mounted to a rear end of a base member of the circular saw. A housing with a saw blade is pivotally connected to the universal arm. A drive device is longitudinally mounted to the housing for driving the saw blade and includes a casing secured on the housing. A motor is securely received in the casing and radially corresponding to the saw blade along a moving direction of the saw blade. A worm is longitudinally secured on a free end of the shaft extending from the motor. A worm gear is laterally rotatably mounted to the casing and engaged to the worm. An endless belt is mounted and surrounding a first belt wheel extending from the saw blade and the second belt wheel extending from the worm gear for driving the saw blade when the motor is operated.

Abstract: A portable saw table for supporting a portable saw. The portable saw table has a base supporting a plate slidably mountable thereon, and the portable saw is attached to the plate. An adjustable work support is mounted on the base adjacent the plate, and an extendable work support is slidably mounted with respect to the base. Linear guides mounted between the base and the plate properly locate the plate with respect to the adjustable work support, thereby permitting a saw fence to be aligned with a vertical guide surface on the adjustable work support. A locking device is used to secure the plate at its aligned position. The adjustable work support is movable lengthwise to align a horizontal work surface immediately adjacent a saw table, and the adjustable work support is also movable in a vertical direction so that it is coplanar with the saw table. The extendable work support is movable in three mutually perpendicular directions to align it with the adjustable work support.

A second embodiment of the saw includes a table having a top surface, the top surface having a first plane, a fence attached to the table, the fence having a front surface extending along a plane substantially perpendicular to the first plane, a first rail fixedly attached at least partially underneath and extending forwardly from the table along a first direction, and a saw unit slidably disposed on the first rail, wherein a user moves the saw unit along the first direction towards the table to perform a cutting operation. Preferably, the fence is rotatably attached to the table.

Abstract: A machine for the trimming of a pipe bend held in a die in a machine frame has two hydraulic rams mounted at 45.degree., the piston rod of each ram carrying one of a pair of rotary cutting devices for trimming respective ends of the pipe bend. Under the two hydraulic rams there are arranged, each on a respective inclined guide way and likewise at an angle of 45.degree. in the machine frame, movable swarf or burr removing chamfering devices moving to bring their rotary cutter head coaxially into engagement with a respective trimmed end of the pipe bend.

Abstract: A process for finishing a 15.degree. to 180.degree. pipe bend which has been preformed on a pipe bending press comprises submitting a preformed pipe bend at a temperature of 700.degree. to 900.degree. C. at which it leaves a pipe bending press to a hot sizing operation which includes trimming both ends of the pipe bend to precise dimensions to eliminate further finishing.

Abstract: A cutting machine to form a tenon at each end of a piece of timber, which tenon has opposite faces which are inclined both longitudinally and transversely relative to the piece of timber and form hereinafter called skew tenon faces. This tenon cutting machine is of simple and inexpensive construction and uses a pair of circular saws which are simply arranged angularly relative to each other and to the piece of timber to produce both skew tenon faces at each end of the piece of timber by simple bodily displacement of the circular saws transversely of the piece of timber. This machine includes a carriage displaceable in a predetermined direction and carrying the two circular saws, a timber carrying bench to place the piece of timber lengthwise orthogonally to this direction and laterally slanted either way in this direction. The displacement of the carriage causes the saws to cut the two surfaces respectively which are required on either side of the tenon.
