A cutting apparatus cuts a fabric using a rotary blade and a fixed blade that are built into a cutter head. The fixed blade is linked, to the other-end side of a swing arm of which one end is pivotally fitted on a blade frame by a swing shaft. The fixed blade is urged by a coil spring connected to the one-end side of the swing arm. When a prescribed resistance force is applied to the fixed blade, a position sensor detects movement of the swing arm, a fixed blade drive cylinder drives the swing arm in response to the detection, and the fixed blade is moved to an accommodation position that is above the position during cutting and that is on an opposite side in the advancing direction of the cutter head.

A device and a method for cutting a loaf of bread in slices having an input compartment adjacent to a set of parallel oblong blades which can be driven back and forth in their longitudinal direction. A pusher movable between a retracted position in relation to the blades and an end cutting position pushes the bread through the blades. A detector is provided to detect the presence of an object in the access opening of an input compartment which cooperates with the blades' drive to stop the movement of the blades when the presence of an object in the access opening is detected. When the presence of an object in the access opening is detected while the pusher is in its retracted position, the movement of the blades starts and the pusher will be moved from its retracted position to the end cutting position when the object is no longer detected in the access opening.

A safety system prevents cutting machine operators from being accidentally carried through the infeed chute into the machine's cutting mechanism. An operator wears a safety device on his wrist and/or ankle and a sensor array mounts on opposing sides of the cutting machine's infeed chute. The sensor array elements are wound in opposite directions and connect in series opposing. The magnetic field of the safety device induces a current in the sensor array as it moves in the proximity of the sensor array. The safety system generates a signal which is proportional to the sum of the induced currents. When the signal exceeds a threshold, the safety system shuts off power to the feed mechanism and/or the cutting blades of the cutting machine, preventing injury to the operator.

The trimmer includes: a pusher 2 that pushes the bound material 1; a pusher moving device that moves the pusher; a positioning part 111 that positions the bound material pushed by the pusher; an allowable position memory that memorizes an allowable position range relevant to the pusher; an allowable reaction force memory that memorizes an allowable reaction force range relevant to the pusher; and a determiner that determines whether a length of the bound material is normal or abnormal. The determiner determines that: the length L of the bound material is normal; or the length L of the bound material is abnormal.

The disclosure provides a handheld power tool, which at least includes a housing assembly, a handle assembly and a switch assembly. The switch assembly includes a button assembly and a push-pull assembly. When the push-pull assembly is configured to complete at least two actions, the button assembly is unlocked, the first action is to slide back and forth along the handle assembly, and the second action is to slide back and forth obliquely along the handle assembly. With the handheld power tool of the disclosure, a trigger switch can be unlocked by a palm, so as to improve a problem of poor comfort during use caused by unlocking the trigger switch by a thumb.

Protective garments are provided. A protective garment includes a protective garment fabric. The fabric is formed from a plurality of layers. At least one layer of the plurality of layers is formed from a plurality of fibers adapted to entangle with a moving blade of a tool upon contact between the moving blade and the fabric. At least one layer of the fabric includes metal fibers. The garment includes a garment sensing device including a sensor configured to detect when one or more metal fibers are cut, and a signal generator configured to send a signal to the tool to disable movement of the moving blade.

A cutting machine includes a platform, two supporting elements, a guiding plate, a handle and a blade assembly. The supporting elements are supported on the platform. Each of the supporting elements includes a space. The guiding plate is inserted in the space of the first supporting element and includes a slot. The handle includes a pivoting plate and an axle. The pivoting plate is inserted in the space of the second supporting element, and includes a primary aperture and a secondary aperture. The axle is inserted in the primary aperture of the pivoting plate and an aperture of the second supporting element. The blade assembly includes a blade and two pins. The first pin is inserted in an aperture of the blade and movably inserted in the slot. The second pin is inserted in another aperture of the blade and the secondary aperture of the pivoting plate.
