Abstract: A web of coherent labels or coherent blanks of wrapping material is advanced along an elongated path toward a severing station where the web is cut at selected intervals by an orbiting knife in cooperation with a stationary or moving knife to yield a succession of sections of desired length. If the web is to be arrested for a shorter or longer period, it is first accelerated above its standard speed and is thereupon decelerated to zero speed during the last interval of advancement so that the length of the leader of the web extending beyond the severing station matches the desired length. Analogously, when the web is restarted, it is accelerated above the standard speed and is thereupon decelerated to such standard speed during the first interval of advancement so that the knives sever a section whose length again matches the desired length.

Abstract: A stamping and forming machine positively prevents slug pulling by stripping the slug off of the end of the punch as the punch is being withdrawn from the die opening after a blanking operation. This is accomplished by providing a die insert support in supporting contact with the die insert having an opening that is identical to the opening in the die insert, but that is rotationally or laterally displaced therefrom by a small amount. As the punch pushes a slug through the opening in the die insert, the slug encounters the displaced opening in the die insert support and is shifted slightly as it is forced into that opening by the punch. As the punch is withdrawn from the die insert opening, the shifted slug cannot return through the opening and is stripped off of the end of the punch.

Abstract: During the feeding of offset continuous collated business form webs to the slow rollers of a burster, it is important to insure that the top web properly passes through the slow roll section. By providing a number of puller wheels having aluminum cores and sawtooth rubber coverings atop conveyor belts passing over crowned pulleys which are oversped relative to the web speed, proper feed to the burster is provided. Form deflecting fingers extending from the puller wheels to the burster also help. In order to prevent the conveyor belts from running off the crowned pulleys an aligner is provided which has a number of vertical dowel pins with plastic sleeves covering and rotatable with respect to the dowel pins, disposed on each side of a conveyor belt associated with a crowned pulley and puller wheel. The aligner is provided immediately upstream of a rubber covered drive roll for the conveyor belts.

Abstract: In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) at least two helical pressure springs (57, 58) act between the two frames (12, 31) and are each arranged in a circumferentially closed duct (45, 46) provided in one (31) of the two frames (12, 31), which duct also accommodates a piston-like pressure member (47, 48) which projects from the relevant duct (45, 46) and bears against the other one (12) of the two frames (12,31).

Abstract: A razor head is advantageously formed with a spacer that is capable of expanding after manufacturing assembly to provide a tighter blade package.

Abstract: The aeration field of an aerator membrane is formed by perforating the membrane with a rotary device having a plurality of perforating tools. The membrane also rotates while it is being perforated, and the membrane and tool simultaneously move in a radial direction, with respect to the membrane, so that a spiral line of perforations results.

Abstract: A ball lock punch and die retainer comprises a single piece body of high strength through hardened tool steel having a relieved flat bottomed borehole for the punch. The exterior sidewall of the retainer opposite the end having the punch borehole is substantially half-cylindrical. The oblique spring hole in the retainer body includes a circumferential undercut in the wall of the spring hole. The undercut mates with an enlarged portion of the spring to prevent the spring from pushing out of the hole.

Abstract: A display arrangement comprises a dancing body torso of plastics material. The lower and upper display halves of the torso are spaced apart. The upper display half is pivotally supported by a support carried by the lower display half. A motor secured to the support is coupled to the upper display half to cause it to oscillate about is pivotal axis. A support bracket secured to the support and the lower display half has a pair of feet which can be secured to a ground engaging member.

Abstract: A workpiece support member has at least one straight edge, and a guide rail extends along the edge. A beam holder is mounted for movement along the guide rail and supports a transverse beam member. The free end of the beam member supports a blade holder, and a blade is removably mounted in the blade holder. The distance between the blade and the guide rail is adjustable.

Abstract: A traversing circular saw device comprising a saw blade assembly mounted onto a cradle to receive a number of logs to be cut into sections. The saw blade assembly comprises a circular saw blade mounted onto an extension arm which is contained within a pivoting arm sleeve. The width of the cradle is greater than the diameter of the saw blade. The saw blade is pivoted down into the cradle by a first piston, and the blade is then extended across the cradle by a second piston.

Abstract: A printed paper dispensing and severing apparatus includes an elongated paper to be printed, dispensed and severed. A printer including a positive drive mechanism projects paper along a guide path to an exit chute in a housing, the guide path being defined at least in part by a deflection plate so that the projection of the paper will encounter the deflection plate and be guided to exit the housing. A cutting mechanism adjacent the guide path includes a blade with a centrally peaked ridge in a guide surface generally parallel to the guide path. The reliability of this mechanism is dramatically improved due the absence of moving parts in the guide path, cutter blade, deflection plate and exit chute. The guide path and the exit chute are angled to one another, the elongated paper is provided in the form of a roll of paper which gives the paper a curl and the curl of the paper is in the same sense as the angle.

Abstract: A work bench (10) such as a miter/bench saw comprises a fixed table (16) having a rotatable platform (15) rotatably inserted in an opening in the fixed table. A clamp (72) for clamping the rotatable platform at a fixed angular position relative to the fixed table comprises a cut (70) extending through the table and extending outwardly from the circular opening in the table to an edge of the table. A lever (72) presses together the edges of the cut so that the circular opening grips the rotatable platform thereby clamping the rotatable platform at a fixed angular position.

Abstract: A lever locking knife with reversing blade having a handle with a slotted recess therein for removably receiving the blade, the handle having a lever pivoted from it, now the blade having a notch that receives a portion of the lever when the lever is in the closed position to hold the blade either in the extended, usable position, or received within the handle recess.

Abstract: An anvil for use in surgical fastener applying apparatus includes an indentation extending lengthwise along at least one of the side walls to provide increased resistance to bending and to permit the application of longer rows of fasteners. An added feature is the deflection preventing member which projects laterally from the side of the anvil and which engages and abuts a corresponding notch in the apparatus for preventing flexure of the anvil when the fastener is closed onto body tissue.

The cutting head also includes a depilatory applicator through which a depilatory substance may be discharged in the general area of the cutting blade.

Abstract: A blade guide of a guillotine shear for flying transverse parting of strips, particularly steel strips. The shear having a shear housing in which blades fastened to blade supports are movable relative to one another on parallel guide paths for cutting and transversely to the guide paths in the running direction of the strip and at the running speed of the strip. The guide paths are arranged in a guide frame which is movable horizontally in the shear housing and the blade supports in the guide frame can be set in rotation by means of crank mechanisms which are supported in the shear housing and are associated with each blade support.
