Abstract: A method for the manufacture of a slide chart, utilizing high speed, straight line gluing and folding machinery, from a unitary blank having a flat sheet separated into three segments, a first and second segment being provided with openings and forming the faces of the manufactured slide chart, and a third segment having scored lines longitudinally extending therethrough to form a railed slide located between the faces of the manufactured slide chart. The method comprises applying glue to the longitudinal edges of the second or third segment, folding the second and third segment onto each other, applying glue to the longitudinal edges of the first or third segment, folding the first and third segment onto each other, and trimming the transverse edges of the resulting slide chart assembly, thereby freeing the slide to move between a pair of rails and the faces of the slide chart to provide a finished slide chart of substantial precision.

Abstract: There is disclosed a positioning head for cutting and marking apparatus, whereby when a plurality of cutter wheels or marking-off wheels are successively moved into place, the positioning head or heads which have already been positioned in place can be locked in place. The positioning head comprises, within a housing mounted on the boss of the cutter or marking-off wheel and slidably fitted on two guide bars, a feed gear threadedly engaged with a feed screw shaft which is extended through the housing, an input gear slidably mounted on an input shaft which is extended through the housing, a group of driving gears for transmitting the rotation of the input gear to the feed gear, and a clutch for connecting and disconnecting the driving force transmitted to the feed gear from the input gear, whereby after the positioning head has been put in place, the clutch may be disengaged so as to lock the positioning head in place while any other positioning head is being moved.

Abstract: The invention relates to a pack, in particular a cuboid cigarette pack, of stiff paper, cardboard or the like, with several flaps of differing transverse and/or longitudinal size which are folded over one another in layers and may or may not be bonded to one another.

Abstract: A method and a machine for producing a latticework structure composed of cells of essentially parallelepipedon shape from e.g. paper coated on one side with synthetic resin. The web is formed over a mandrel into a sleeve of square cross-sectional shape while being successively advanced, and the sleeve is cut into bits which are flattened and by a step-by-step feeding mechanism positioned adjacent one another with one bit overlapping the following one over halfway in the transverse direction. The bits are bonded together while so positioned whereby flat elements are formed. 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.
