Abstract: Self-sticking note pads are mass-produced in a continuous operation starting with a running web of paper which is drawn from a roll and one side of which is coated with longitudinally or transversely extending stripes of adhesive before the web is subdivided into a series of large panels which are gathered into stacks and overlapped by bottom covers prior to subdivision into pads of desired size. The stacks are preferably inverted prior to subdivision into pads so that the bottom covers are disposed below the lowermost panels of the corresponding stacks, and the subdivision of successive stacks into pads takes place in two immediately following stages. The pads are transported to a packing machine.

Abstract: A method and apparatus for forming multilayer ceramic substrates from large area ceramic green sheets, each having an array of layer sites thereon, by serially aligning each individual layer site with respect to a die cavity and punching the aligned layer site into the die cavity to thereby stack the requisite number of aligned layer sites. Individual layer site alignment ensures that each layer site is aligned with respect to the die cavity so that the dimensional tolerances between layer sites on the large area green sheet are eliminated. Thus, as large a green sheet as is cost effective may be employed, notwithstanding the fact that dimensional distortions on the large area green sheet would preclude alignment of corresponding layer site vias on superimposed large area green sheets.

The completed stack is discharged in a perforating station where the tearing line is perforated simultaneously through all stacked bags. If desired, additional holes are punched between the upper edge of the bag and the perforation line.

Abstract: An arrangement for fabricating planar elements which may be stacked for producing predetermined surfaces and bodies. The planar elements have cross-sections corresponding to respective cross-sections of the surface to be constructed. The planar elements are formed by cutting them from plate-shaped material or sheet metal, and the cut-out elements are held to the parent sheet or plate material by tabs. The planar elements are cut successively from the sheet or plate-shaped material at spaced intervals. The cutting action is such as to leave the tabs for holding the planar elements in place. Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located.

These flat elements are stacked on top of one another by a mechanism ensuring that the elements are displaced by one cell width in their longitudinal direction and the stack of elements is then cut into pieces having the desired height of the cells. When extended, these pieces form the desired cellular latticework structure.

Abstract: The present invention relates to apparatus for forming a series of shingles from two shingle members. In the past such apparatus has required an inordinate number of hand operations and warehousing of such shingle members. These hand operations and warehousing functions have resulted in a substantial number of non-conforming shingles, which must be rejected, and also causing other problems which affect the overall productivity of such prior art apparatus.
