The machine includes a feeding path for the logs to be cut and a cutting head arranged along the feeding path. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes at least a grinding unit, including at least one grinding wheel mounted onto a rotation shaft and co-acting with a side of the disc-shaped cutting blade to grind the cutting edge of the same disc-shaped cutting blade. A controlled approach system is also provided to move the grinding wheel towards the disc-shaped cutting blade.

A system, a method and a collapsible and/or folding apparatus may use a wire loop to cut an object. The apparatus may have a wire loop connected to pulleys on a carriage attached to a frame. The carriage may move relative to the frame to direct the wire loop through the object. The apparatus may have arms on the carriage that may be folded and/or a kicker frame pivotably connected to the frame that may be retracted to reduce the overall size of the apparatus.

The invention concerns a cutting device (1) for reducing the width of a ready-made roller blind blank (28) comprising a roller tube onto which a fabric has been wound. The cutting device (1) comprises a mandrel (13), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel (13) such that the width of the ready-made roller blind blank (28) is reduced. The invention also concerns a ready-made roller blind blank (28), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device (1) according to the invention. For this the roller blind blank (28) comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank (28).

A conduit gripper and hand guard apparatus, system, and methods of use thereof that includes a two piece cylindrical gripper having a first grip member and a second grip member hinged therebetween to grip the conduit, a hand shield integral with said first grip member to shield the user's hand during cutting of the conduit, said hand shield formed with a slot therein, the slot positioned between a perimeter edge and an interior of said hand shield, and a saw stop protruding from said hand shield, and, thus, functions to be compact, enables gripping of the conduit for positioning and measurement, enables safe standup cutting of the conduit.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.
