Abstract: A method and apparatus for producing an array of individual business forms from a web allow two or more sets of forms from a single web to be formed and integrated in a final array, preferably an in seriatim array with a spacing between the individual forms. A web at least two sheets wide is moved in a first direction and slit to produce at least two web sections. The two web sections are redirected so that they move in different paths, such as by stationary curved surfaces that are vertically spaced from each other and disposed at different angles to the horizontal. Typically the web sections are redirected so that they are substantially vertically aligned with each other. Then the two web sections are cut into individual sheets and the individual sheets are redirected and combined into a single array of sheets with alternating sheets in the array from alternating web sections.

Abstract: A guide is provided for a string trimmer that permits it to be positioned closely adjacent to or in a variety of positions further from borders and similar objects. The guide is attachable to the guard of the trimmer and is composed of two slideably adjustable members that permit its length to be varied to provide different spacings from borders and objects. The guide includes an obtuse angle formed in its length to permit it to be used vertically as an edger and vary the spacings from borders when it is used as a horizontal trimmer. An elliptical head is provided on the outer end of the plastic guide to facilitate fine spacing adjustments and enable sliding movement along a variety of surfaces such as pavements, stones and gravel.

Abstract: The guide shoe according to the invention for cutting machines with a pintype drive has an insertion pocket in which a coupling piece engages from above, which coupling piece is arranged on a guide arm of the cutting machine and to which the guide shoe is attached so as to be pivotable by means of a transverse bolt which passes through the insertion pocket. In order also to allow the guide shoe to be pivotable about a vertical axis, the coupling piece is provided with an upright vertical journal which engages from below in a corresponding bearing hole on the guide arm. In this case, in a preferred embodiment, the bearing journal is decoupled from transverse forces which are transmitted between the guide arm and the guide shoe via a transverse-force piece arranged on the coupling piece.

Both the top cutting edge and the bottom cutting edge have a compound curve containing two radii of curvatures which are different from one another.

Abstract: A frozen hamburger patty separator for separating a single hamburger patty from a frozen hamburger block including a U-shaped holding member having a bottom wall connected to front and rear walls for holding a frozen hamburger block in place. A U-shaped handle support component is connected to the holding member, and a blade support component is pivotally mounted on the handle support component. A separator blade is connected to the blade support component and is less than 2 inches from the pivotal mounting. A handle is connected to the blade support component for pivotally moving the separator blade between a separating position for separating hamburger patties from the frozen hamburger block and a non-separating position for allowing the frozen hamburger block to be moved along the holding member for holding the frozen hamburger block.

Abstract: An apparatus for punching out pockets in a roller cage for rollers is provided with two simultaneously movable male dies whose outer cutting edges in the circumferential direction are spaced apart from one another by at least about 0.4 times the cage diameter. These male dies are preferably operative from the interior of the cage and each punches slightly more than half the pocket width. By indexing the cage by one pocket division each time, the pockets are punched out completely. In each punching increment, they receive the runup face for the roller over their entire length, which runup face need not be further machined.
