Abstract: A rectangular insert of cutting material having top and bottom surfaces intersected by longitudinal edge surfaces to form four main longitudinal cutting edges. The top and bottom surfaces have ribs normal to the edge surfaces at each corner and sinusoidally spaced ribs normal to the edge surfaces starting at graduated distances from each corner rib so that when the inserts are stacked edgewise in different index positions, the corner ribs register with each other and the other ribs are out of phase with each other. The ribs of the cutting edges all extend edgewise of the bit or in the width direction so that the width of the insert is available to take the cutting thrust.

Abstract: A tray forming machine comprising an infeed station for accepting a blank of corrugated plastic, and a transfer mechanism which automatically conveys the blank along a plane into a blank receiving station between a tray forming ram and a forming tool frame. The tray forming ram moves downward along a vertical path carrying the blank through the forming tool frame, during which the blank is folded into a generally upright tray configuration by a series of vertically displaced side and end forming bars and brackets. The tray forming ram and blank emerge from the forming tool frame and are received in a clamping and welding assembly which holds the blank in position while it is secured by sonic welds into the upright tray. The clamping assembly releases while the tray forming ram returns to its raised position, and the tray is stripped off the tray forming ram by the bottom of the forming brackets.

Abstract: A center-drive lathe has a longitudinally elongated machine base having a front, a back, and a pair of longitudinally spaced ends. A centerstock is generally centrally mounted on the front of the base and a pair of guides on the front of the base extend longitudinally at least from the centerstock to the ends of the base. Respective carriages are displaceable longitudinally along the guides between the ends and the centerstock so that a workpiece can be spanned in and rotated by the centerstock and worked by tools held on the carriages. A stack of interconnected telescoping plates including one end plate connected to one of the carriages and another end plate connected to the other carriage extends over the guides and past the centerstock between the carriages. The guides are thus covered between the carriages by the telescoping stack of plates.

Abstract: A face milling cutter for holding a plurality of cemented tool bits for rotation about an axis and an associated method utilize a body of material defining a shank portion securable within a rotatable spindle of a machine tool for rotation about an axis and an insert-accepting body portion within which the tool bits are supported. The insert-accepting body portion is generally cylindrically in shape and joined to the shank portion so that the longitudinal axis of the body portion coincides with the axis of rotation of the cutter. Furthermore, the body portion defines a plurality of radially outwardly-opening recesses extending along the length of the cylindrical periphery of the body portion. Each recess is adapted to accept the shank of a tool bit so that when operatively positioned therein, the tool bit shank extends generally longitudinally of the cutter body portion.

The center insert which is made of cemented carbide has cutting edges passing through the center axis. The cutting inserts are made of a super hard sintered compact. Each of the cutting inserts has a cutting edge aligned to the cutting edge of the center insert. The cutting edges of the cutting inserts and the center insert cooperate to draw a hemispherical path on rotation.

Abstract: A device for cutting a support helix for a radially expanded sleeve of resilient material which may be used as an enclosure of an elongate object such as an electrical cable. The device includes a knife wheel having a plurality of circumferentially distributed, radially projecting knives for making elongate spaced cuts through the wall of a plastic tube. The plastic tube and the knife wheel are rotated and moved axially relative to each other to cause the knife wheel to make a helical pattern of elongate spaced cuts through the wall of the plastic tube along the entire length of the plastic tube. One end portion of the helix is separated from the helix into a strip extending from one end of the helix through the support helix and out of the other end thereof where it may be manually grasped. The connection areas between the spaced cuts are dimensioned so that the support helix can be manually unwound by pulling on the end portion extending through the support helix.

Abstract: When blanks for producing (cigarette) packs are made in the region of the packaging machine itself, especially by being severed from a web of material (12), the blank production must be matched to the performance of the packaging machine. For severing blanks (10, 11) from a web of material (12) having stampings, perforations, etc. drawing rollers (25, 26) and conveying rollers (33, 34), on the one hand, and tearing rollers (27, 28 and 35, 36) running at a higher speed, on the other hand are used. The blanks (10, 11) are torn off as a result of the difference in the conveying speed. In the simultaneous processing of two blanks (10, 11), units (23) comprising two blanks (10, 11) are first servered from the web of material (12) and these are then divided into individual blanks (10, 11) which are conveyed further, especially fed to a folding turret (20).

Abstract: An auxiliary-function hydraulic system is provided for a computerized numerical control (CNC) machine tooling unit. Hydraulic power is provided for locking collet or chuck to an open or closed position and providing an affirmative collet-open and/or collet-closed signal to communicate the collet position to the host computer. The tailstock can be brought gently forward to contact a workpiece and can be returned rapidly to the home position, with a break-away pressure feature being employed to overcome initial static friction. A pressure switch indicates that the tailstock is in position against the workpiece. A spindle brake applies braking to the spindle to stop the same from high speed either on command or in the event of system failure. In the latter case, braking occurs prior to loss of pressure to the collet closer cylinder. Also, a turret clamp locks and unlocks a tool changer turret.

Abstract: For centering optic lenses in a mechanical mounting, in particular during an edge cutting and bevelling, the invention includes a device having a housing (10), a drive (M, R, 14/14', 16/16') for a lower centering spindle 18 and an upper centering spindle 18' with an interpositioning of a torque divider (50). The centering spindles are held in axial alignment by guiding and clamping bearings (22, 22') and carry clamping cups (20, 20'), between which clamping cups the lens (L), which is to be machined, can be clamped. A clamping device (24) is for this purpose connected parallel to a membrane piston (32), which assures a precise stepped moving of the lower centering spindle 18 in an axial direction (A) to the upper centering spindle (18'). A short-stroke piston (38) exists in each pressure cylinder 28, which short-stroke piston (38) is followed by a long-stroke piston (40) having a bore (42) extending therethrough.

The anvil is secured in an axially oriented slot which includes an arcuate seating face. Rotation of the anvil within the slot effects radial adjustment of the insert.

Abstract: A system of hand-held lathe tool assemblies especially for executing large scale deep and/or hollow work efficiently and rapidly while minimizing operator fatigue. Tool working portions may be integral with their carriers or holders or may be selectively connected to them by means of a conventional chuck or collet. The butt portions of very long lathe tool assemblies permit the turner to apply forewarm and/or upper body to the tool and gain sufficient leverage to work comfortably and hence with enhanced control while performing large scale work with tool reaches from rest to tool cutting point as high as 36 inches in length. A "slicer" tool facilitates separation (and conservation) of large volumes of material without comminution in the rough shaping stages of work. Other tool forms are disclosed.

Abstract: A roller burnishing device for sizing and/or finishing the external surface of a workpiece having a circular sectional contour by causing a relative rotation between the workpiece and a plurality of truncated conical rollers arranged within a head having a truncated conical inner surface. In this device, the head is made nonrotatable and instead a hollow cylindrical cage supporting the rollers within the head is driven in rotation to rotate the rollers at a high speed and the rollers are caused to orbit by driving the cage in low speed rotation thereby causing the rollers to make a planetary motion within the head.

Abstract: A bar puller is provided having adjustable jaws comprising fingers made of a resilient material. The fingers extend forward from a housing adapted to be mounted at a tool station of a computer numerically controlled lathe having a turret. Front and side guiding surfaces are provided on the ends of the fingers to cause the jaws to deflect outwardly and grip a bar when forcibly engaged therewith. The lathe chuck releases the bar allowing the bar puller to withdraw the end of the bar a desired distance out of the chuck. The chuck is closed while the turret continues moving away from the chuck causing the bar to be withdrawn from between the jaws of the bar puller, readying the machine for its next cycle.

Abstract: Plastic bag are stacked as they are received from a bag making machine by a radial arm transfer wheel whose suction arms engage the bags by transferring edges thereof and with the ends of the arms so that the bags are pressed onto needles of needle bars on a needle bar basket. The needle bars are rotated, with the bags suspending therefrom the spindling position through an intermediate position into a smoothing and removal position in which the hanging stack is lifted to a horizontal orientation and smoothed by a beam movable above the stack and having a smoothing brush engaging the stack. In this latter position a stripper is shifted past the needle bar therefrom. The stack is carried away by a clamp.
