Abstract: A packaging container is closed by using a double seam 152 to secure over the container body 70 a cover 74 of smaller diameter than is usual, creating a radial space 104 around the cover chuck wall 122 into which the body sidewall 72 is deformed to form a neck 76. The cover is initially placed on the body to form a sealable interface 142 therebetween, this interface being preserved throughout the seaming process. The body and/or the cover may be of plastics or metal or a laminated material. In an aseptic packaging process, a primary seal is created at the interface 142 under sterile conditions, seaming subsequently being carried out under non-sterile conditions.

Abstract: An apparatus which moves a tool back and forth in synchronism with rotation of a workpiece with respect to the workpiece to machine the workpiece into a non-circular shape. The tool is attached to a tool mount placed on a tool mount table which is connected to be moved in a direction perpendicular to the axis of a spindle by a motor. The tool is connected to be moved in a direction perpendicular to the axis of the spindle with respect to the tool mount by a high speed actuator. Profile generating movement of the tool is thus provided by a combination of movement provided by the motor and movement provided by the high speed actuator. The high speed actuator is controlled in accordance with high frequency components included in profile data while the motor is driven in accordance with low frequency components included in the profile data. As a result, the responsiveness in profile generating movement of the tool is improved, and high speed machining of a non-circular workpiece is enabled.

Abstract: A turret lathe table having tool holders arranged on at least three concentric reference circles around the center of the table. The tool holders consist of first tool holders for drill tools and inner turning tools and second tool holders for outer turning tools. The first tool holders are arranged exclusively on the innermost and at least one intermediate reference circle, while the second tool holders are arranged only on the outermost reference circle. The spacing between the tool holders is such that a collision-free diameter remains between adjacent tool holders, the collision-free diameter being defined as a diameter equivalent to a workpiece of maximum dimensions capable of being machined by a respective tool in a respective tool holder without interference from tools in adjacent tool holders.

Abstract: A throw away cutting tool comprising a holder formed with a wedge groove and a throw away insert having a cutting edge at one end thereof and a wedge portion at the other end, the wedge portion being adapted to be clamped in the wedge groove by elasticity of the material of the holder. The holder is at least partly made of cemented carbide for higher rigidity and cutting stability. Also, the radius of curvature at the deep end of the wedge groove is optimized for crack resistance. Further, the angle of the V-ridge on the holder is interrelated to the angle of the V-groove in the insert for more holding stability and crack resistance.

Abstract: A cut and score die apparatus is provided for progressively converting a sheet of material into blanks. The apparatus includes a punching section for punching scrap material from the sheet of material to define an array of interconnected blanks arranged in a grid of rows and columns on the sheet of material. A scoring section is provided for simultaneously scoring a first predetermined pattern on a trailing portion of a first row of blanks and a second predetermined pattern on the leading portion of a second, succeeding row of blanks on the sheet of material. A blanking section is also provided for piercing the sheet of material in a predetermined pattern to cut blanks from the sheet of material without producing any additional scrap material.

Abstract: In the production of (cigarette) packs of the hinge-lid type, supplying a sufficient amount of material to the packaging machine presents a particular problem. In an advantageous solution, blanks (20) for producing the packs are severed from a continuous web of material (24) with punchings for delimiting the blanks (20) and further processed within the packaging machine. For the efficient production of (individual) blanks from the continuous web of material (24), the latter is fed to a blank station (26), in which preferably two respective blanks (20a, 20a) lying next to one another are severed by shearing from the following web of material (24) and from one another by means of severing rams (29). The two blanks (20a, 20b) so formed and individually separated are then fed to a folding turret (40), specifically appropriately with an intermediate conveyor in the form of a rotating blank turret (43) being interposed.

Abstract: Apparatus for positioning a block which may be used as a charger for a lathe. The apparatus includes opposed primary chucks, each taking the form of a tapered receptacle for receiving the end of a block. The primary chucks are each displaceable in x and y directions extending laterally of a rotation axis, to position a block in an optimum position for peeling veneer therefrom. A secondary chuck is associated with each primary chuck which extensible to grip a block independently of the primary chuck.

Abstract: Process and apparatus for the stocking (storage) of (pack) blanks and for feeding these to a folding unit of a packaging machine. The supply of packaging material to a packaging machine is especially difficult in the processing of blanks made of cardboard. Supply becomes easier if blanks joined together via residual connections are conveyed as a web of material in the packaging machine. Especially favorable storage of blanks (11) connected to one another is possible if the web of material (19) so formed is arranged in a zigzag-shaped manner as a result of oppositely directed folding and the blanks are stacked in this way. The stacks (15) formed can be kept in stock in a space-saving way and fed to an extraction station, in which the web of material (19) is drawn off from the stacks (15) and restored to the extended state. Appropriately, a plurality of stacks (15) is connected to one another, specifically via vertical web portions (23) from one stack to another, to form a continuous web of material (19).

Abstract: An abrasive honing stick is bonded within a channel-shaped shell which is made of sheet metal and which is secured detachably to a stone holder by a pair of retaining studs. Each stud extends through a hole in the shell, is telescoped into an alined hole in the holder and is clamped by a set screw which, when tightened, cams against the stud to draw the shell inwardly against the holder. The retention studs extend radially from the shell to reduce the circumferential dimension of the overall stone assembly and thereby enable a comparatively large number of assemblies to be placed in a hone body of a given diameter.

Abstract: An apparatus for stripping the scrap portion from a die cut blank includes a stripper pin carrier providing a pattern of stripper pins supported in a resilient compressible material layer in which the stripper pins are demountably embedded. The stripper pins may be inserted into the reslient layer to provide a pattern or patterns which will accommodate virtually any size, shape and location of scrap portions to be stripped from a blank. The stripper pins can be removed and reinserted in a different pattern to accommodate a different run of blanks of corrugated paperboard or the like. Programmable robotic control may be used for pin placement and removal. The stripper pin pattern, location and rotation are synchronized with operation of the upstream cutting die such that the die cut blanks move continuously under the stripper roll for automatic scrap stripping.

Abstract: An adjustable wrench has a stationary jaw formed at an end of a handle. A slidable jaw is mounted for linear reciprocal movement toward and away from the stationary jaw by a worm gear in mesh with a gear rack on the slidable jaw. An axially movable shaft extends through the worm gear. The worm gear is rotatably mounted on the shaft, and restrained against axial movement relative thereto. An inner end of the shaft is slidably received in a recess in the handle, and a coil spring in the recess outwardly biases the shaft. A lever has a first end pivotally mounted to an outer end of the shaft and an intermediate portion pivotally secured to the handle. The slidable jaw may be moved by rotation of the worm gear to a loosely adjusted position and may be firmly tightened into engagmeent with the head of a fastener by manipulation of the pivotal lever. The wrench allows extremely quick engagement and release with the head portions of various fasteners.
