Abstract: A variable-velocity drive is provided which serves to so control the periral velocity of a window cutter roller in an envelope machine working from the reel that, irrespective of the developed length of such roller, the velocity of the window cutter is the same as that of the paper web for the time that such cutter is operative on such web. To this end, the variable-velocity drive is basically devised from a number of universal joints interconnecting shafts whose axes intersect one another at an angle of up to approximately 45.degree.; the universal joints are so offset from one another in rotation that the variations or irregularities arising in the discrete joints are superimposed upon one another so as to have an amplifying effect. Since any one such universal joint arrangement passes through two velocity maxima and two velocity minima per revolution, gearing is provided on the input and output side to make the universal joint arrangement run at half the cycle speed.

Air passages are also provided in the side of the vacuum cylinder opposite the control head to connect the last attenuation chamber to the atmosphere.

Abstract: There is provided an absorbent hygienic article of generally "e" shaped cs-section with inserted superabsorbent layers, the article being stepped in a frustum shape at its front and rear ends. There is also provided a method for manufacturing the article, the blank for the article being devised individually on a flock wheel and comprised of a central member, a long side member and a short side member both disposed symmetrically about the central member. The blank is then subject to two folding steps to produce it, superabsorbent layers being applied before each of the two folding steps.

Abstract: Confectionery solution containing gelling agents such as agar-agar, tends ry markedly to form streamers or tails when being poured. The formation of tails or streamers is inhibited in accordance with the invention by the atmosphere in the environment of the pouring region being maintained at (a) a temperature at least equal to the temperature of the confectionery solution and (b) a moisture content at least equal to the equilibrium moisture of the confectionery solution.

Abstract: According to the invention, separator plates bevelled at the front edges provided on the rotating feed segments of a sheet feeder, more particularly for envelope machines, which finally separate from the pile of blanks a blank for feeding, the front edge of the bottom flap of the blank having been separated from the pile by means of a tongue and vacuum device. The separator plates align the blank in the direction of conveyance, smooth it out, and then feed it to the extractor roller and engagement edge of the rotating feed segments.

Abstract: There is provided a sheet pile replenishment apparatus in the form of a cined unstacking and restacking device for lifting a sub-pile of sheets from a supply pile of sheets, conveying and depositing the sub-pile on a pile of sheets on a feed pile plate of a sheet feeder of a processing machine, such as an envelope or bag machine. The apparatus includes a separating roller, disposed at an adjustable angle, which separates the sub-pile from the supply pile of sheets, a clamp for engaging the sub-pile, a table of comb-like construction for conveying the sub-pile, vibrating aligning pins for exactly aligning the sub-pile, and means for depositing the sub-pile in an exact position on the pile of sheets ready for feeding by the sheet feeder to the processing machine.

Abstract: A process and apparatus for pouring confectionery solution is provided. The pparatus basically comprises a supply tank heated to approximately 80.degree. C., a dosing system, a nozzle plate and heating means. The proportion of the confectionery solution which is branched off from the supply tank for a pouring operation receives heat as it passes through the dosing system and/or the nozzle plate.

The punch is characterized by the provision of intermediate bearings with an adjustable member therebetween. This precludes unwanted movements in the bearings between the two rolls due to varying cutting and out-of-balance forces, the adjustable member making it possible to correct the between-axes distance to suit cutter wear.
