To permit continuous adjustment of separating rollers (10, 11) positioned downstream of cutter cylinders (3, 4) cutting sheets (7) from a continuous web (1) during operation of the machine, to adjust for different lengths of cut sheets, and accelerate the cut sheets to the circumferential speed of a gripper apparatus, the separating cylinders (10, 11) are mounted on a first carrier structure (38) which is longitudinally moveable independently of the drive therefore with respect to transport belts (8, 9) passing beneath the separating rollers, the adjustment spacing between the separating rollers being controllable, for example by compressed air cylinders (55). Drives, in order to reduce noise, preferably are by gear belts driven from the cutter cylinders, to provide for synchronized operation of the transport or conveyor belts, the separating cylinders (10, 11) and of subsequent transport apparatus, such as a gripper cylinder (12).

In a method and apparatus for cutting and welding slugs to lead wires, a die has a bore therein through which the slug feedstock is stepwise advanced. The die is ferromagnetic and a permanent magnet is positioned with one magnetic pole adjacent the cutting end of the die. A knife has an opening therein for receiving the feedstock advancing out of the die when the hole and die are aligned. Rocking of the knife cuts free a slug. When the knife is rocked back into alignment, the slug positions itself on the freshly cut end of the feedstock. Advance of the feedstock then pushes the slug out of the knife and presents it to a clamp.

Apparatus for transporting knives, sockets, holders and analogous devices for severing, supporting, transferring and/or otherwise manipulating rod-shaped articles which constitute or form part of smokers' products has first and second disks which are rotatable about parallel axes and carry sets of levers each pivotable about an axis which is parallel to the axes of the disks. Each lever of one disk is coupled to a lever of the other disk by a crank unit one pin of which carries a tool. One of the disks is driven and transmits torque to the other disk by way of the levers and crank units whereby the crank units orbit and their pins hold the tools against any change of orientation. Stationary cams have congruent grooves for roller followers which are provided on the levers of the first and second disks, and the cam grooves are configurated in such a way that the cams can reduce or increase the absolute speed of movement of crank pins by moving the pins toward or away from the axes of the respective disks. The tools can transfer rod-shaped articles from a conveyor which transports the articles axially to a conveyor which transports the articles sideways, or vice versa. Also, the tools can constitute sockets which prop spaced-apart portions of a continuous tobacco or filter rod during severing of the rod. The severing mechanism can employ a second apparatus which is mirror symmetrical to the apparatus whose crank units support the sockets, and the tools of the second apparatus include rotary knives cooperating with successive sockets to sever the rod at desired intervals.

The present invention is concerned with a method of and apparatus for cutting a slab from a body of uncured light-weight concrete, resting on a support surface. The method comprises the step of moving the body of uncured light-weight concrete along a longitudinal axis of said support surface through a predetermined distance; cutting a slab from said body while supporting the front face of said slab, moving the slab away from said body along an extension of said longitudinal axis; and subsequently moving the slab along at least one arcuate movement path in a plane perpendicular to said support surface and parallel to said longitudinal axis. The apparatus for performing the methods includes a sequentially moveable work feed means, a wire cutter mechanism for cutting a slab from the face of the concrete and a carosel-like pneumatic suction device for holding and transporting the cut slab to subsequent spraying, shaping and stacking stations.

Apparatus for processing flat strip material including cutting apparatus for cutting the material and to strip portions and stacking apparatus having air cushion means for stacking the strip portions one on top of the other. An accelerating anchoring roller, having vacuum or magnet devices therein for attracting the sheet portions thereto are provided for the exclusive transfer of the strip portions from the position were cut in the cutting apparatus in positions at the inlet of the stacking apparatus where the air cushion takes over the conveyance and stacking of the strip portions.

The provision in a conventional punch press of a cyclicly-operable transfer mechanism which is adapted to be bolted to the stationary die shoe of the press in between successive forming stations and has associated with it a pair of blank-gripping jaws which travel generally in web line fashion between first and second stations for blank-transferring purposes while at the same time rotating so that each blank is reversed from end to end upon completion of the transfer operation. During the transfer, the jaws swing or revolve in a circular path about a vertical axis so that directional reversal of the jaws accounts for a major portion of the blank displacement. Additional web line jaw displacement takes place at the first forming station in order to bring the jaws while in an open position into straddling relationship with the leading edge of a blank prior to gripping thereof and similar web line jaw displacement takes place at the second forming station in order to withdraw the open jaws from the transferred blank after release thereof. Components of vertical jaw movement during the transfer take place, if required, for the purpose of lifting the blank from the plane of the web and compensating for differences in elevation of the blank at the two forming stations.
摘要:
A method of cutting interconnected packages or articles from a continuous strip is characterized by the step of restraining and controlling the movement of a leading one of the articles or packages while a trailing edge of that package is severed from the strip and then releasing that package in a controlled manner to deposit the same onto an underlying article receiving surface with one side of that package oriented relative to similar sides of previously severed packages in a preselected manner. The underlying surface may include a conveyor operated at a speed controlled to shingle-stack the severed packages for facilitating further handling.
