摘要:
A system of safety devices is disclosed for use in connection with powered cutting tools, including but not limited to table saws, miter saws, jointers, shapers and routers. The devices include a right hand push device adapted to slide along the fence of a table saw, shaper, router or jointer, a dual bearing hold down device to secure a work piece in at least three directions and adapted for use with a table saw, shaper, router or jointer, an anti-kickback device to secure a work piece after a cut is made and while cutting continues and adapted for use with a table saw, shaper, router or jointer, a left hand hold down device for securing a work piece on the side of a cutting blade opposite that of a fence and adapted for use with a table saw, shaper, router or jointer, and a hold down device adapted for use with miter saws. Each of the devices, alone and in combination, protect the operator of the power tools from serious injury from the cutting tool and from work piece kickback.

A dual adjustable feather jig for simultaneously holding a piece of wood stock firmly against a stationary rip fence and against the top surface of a worktable. The feather jig includes a lower feather board with a ‘T’ in channel bar adjustably mounted on the bottom surface of the lower feather board to laterally adjust the lower feather board over the worktable. Mounted transversely on the lower feather board is an upper feather board assembly that includes a vertical feather board to hold the wood piece against the worktable. The vertical feather board is connected to a slider arm that slides longitudinally over a riser block securely mounted to the lower feather board. Formed on the lateral and lower edges of the lower and vertical feather boards, respectively, are diagonally aligned fingers that press the wood piece against the rip fence and against the top surface of the worktable.

The invention concerns a device for die-cutting a stack of sheet-like materials, particularly labels, whereby the stack is pressed into the die-cutter blade by a relative movement of a punching ram and a hollow cylindrical die-cutter blade. For a device such as this, it is proposed that the die-cutter blade 18 is adjustably held in a frame 16, and the frame 16 is accommodated by a receiving apparatus 13 which is mounted in a punch platen 12 and is adjustable relative to it, whereby the frame 16 can be slid in a plane parallel to the punch platen 12, in particular is adjustable in the direction of two major axes that are essentially arranged perpendicular to one another, and can also be tilted out of the plane. Such a device allows for precise orientation of the die-cutter blade relative to the stack to be punched.

The invention concerns a device for die-cutting a stack of sheet-like materials, particularly labels, whereby the stack is pressed into the die-cutter blade by a relative movement of a punching ram and a hollow cylindrical die-cutter blade. For such a device, it is proposed that the stack (8) to be punched be positioned between a limiting element (88) and a moveable slide-in unit 21 is positioned against a stop (89), and the limiting element (88) and the stop (89) are moveable. This type of construction of the die-cutting device ensures an optimal positioning of the stack in area of the pinching ram, independent of varying stack sizes.

The invention provides a slicing and conveying system that includes a slicing blade that cuts slices from a loaf, and an output conveyor located below the slicing blade for receiving the slices in a draft. A control system automatically adjusts a lateral movement of the output conveyor to form a laterally shingled draft of a consistent width in response to a sensed lateral dimension of the loaf being sliced. The control system includes a displacement sensor carried by a laterally adjustable guide assembly adjacent to the slicing blade. The displacement sensor is signal-connected to a control. The control is signal-connected to the output conveyor to control the lateral movement of the output conveyor according to the lateral dimension of the loaf sensed by the displacement sensor. As an additional aspect, the slices can be shingled in the longitudinal direction to form a two dimensional footprint. A length sensor can sense the length of the shingled draft and send a feedback signal to the control to make adjustments to the longitudinal movement of the output conveyor to adjust the degree of longitudinal shingling.

The invention concerns a device for die-cutting a stack of sheet-like materials, particularly labels, whereby the stack is pressed into the die-cutter blade by a relative movement of a punching ram and a hollow cylindrical die-cutter blade. In such a device, a frame 16 with clamping elements 17 mounted in, and adjustable and lockable relative to the frame 16, is provided for fixation of the die-cutter blade 18, and also an adjusting element 70, 72 mounted in the frame 16 is provided for aligned orientation with a minimum of one orientation edge of the adjusting element 70, 72 with one knife edge section 69 of the die-cutter blade 18 prior to fixation of the adjusted clamping elements 17. Pre-adjustment of the die-cutter blade, for the purpose of optimal positioning to the stack to be punched, is ensured in a die-cutting device of this type.
摘要:
An apparatus for separating a ribbon-coated multicore optical fiber at a plurality of positions at once, wherein the ribbon-coated multicore optical fiber includes a number of single-core fibers arranged in parallel. This apparatus comprises a first cutting member in which a plurality of sets of arc faces opposed to each other by way of a through path for inserting the ribbon-coated multicore optical fiber are disposed along the through path, while the arc faces in the respective sets extend from one side section of the through path halfway through the width direction of the through path; a second cutting member having a plurality of arc faces which continuously extend to and are adapted to join with the respective arc faces of the first cutting member in the width direction of the through path; and guide members which are respectively disposed at both end positions of the through path so as to position the ribbon-coated multicore optical fiber inserted into the through path. The first and second cutting members are movable relative to each other in the direction in which the arc faces are opposed to each other.

An apparatus for punching or shearing work members by tool elements which are supported in a holder, with one of the tool elements movable toward and away from the other. The holder is supported in a frame in which a work member is guided between the tool elements. The holder is resiliently supported in the frame so that during a work operation the actuated tool element will first engage the work member and then the holder will move to bring the other tool element into engagement with the work member and the work operation is then completed by continuing the actuation of the actuated tool element.
