Claims priority, application Switzerland July 28, 1948 4 Claims.

This invention relates to the manufacture of upholstered paper and it relates particularly to a machine for the production of this paper type from superposed paper strips.

The number of processes and devices designed to produce an upholstered paper adapted for use in packing articles, which are sensitive to pressure, is very large.

Upholstered paper articles containing an insertion of cellulose or papers and being shaped as stuifed cushions have served this purpose well, these articles consisting of paper layers superposed upon each other and being pasted together.

It is the main object of the invention to present a stamping press for pasting and pressing together paper sheets for use in the manufacture of the upholstered papers.

In conformity with a preferred embodiment of the invention, two circulating endless press bands are provided in a superposed position upon which stamping members are exchangeably fastened. This arrangement ofiers the great advantage of producing diversified patterns with the same machine. The stamping members are provided with the respective patterns. Patterned gumming rollers must be provided to apply the patterns to the paper hands before entering the stamping press.

The machine forming the subject matter of this invention will now be described with reference to the attached drawings showing several preferred embodiments thereof. In the drawmgs,

Fig. 1 is a longitudinal sectional view of the machine;

Fig. 2 is a sectional view on line .r-:c of Fig. 1;

. Fig. 3 is an enlarged longitudinal sectional view. of a machine part;

Fig. 4 is an elevational view, partly in section taken on line ll of Fig. 3;

Figs. 5-? illustrate a front view, a side view and a plan view respectively of a machine detail; and

Figs. 81() show samples of the upholstered paper manufactured in conformity with the invention.

The machine shown in the drawings includes a stamping press having thin endless superposed steel bands, to which stamping plates are fastened.

An electromotor 51 is mounted in a casing 55 forming a part of the machine 'frame (not shown) this electromotor drives shaft "59 by means of a worm gear 53. A switch 60 and a conical clutch :6! actuated by a lever 62 are located in casing 56.

At both sides of the machine frame, pairs of rollers 65, 55 and 66, 66 are mounted on shafts 67, 51 and 68, 68 the shafts are supported between the rollers by bearings 69, 69 and 10, 10 The rollers are driven from shaft 59 extending from the casing 55 through the intermediary of a pair of conical Wheels H; these wheels drive a shaft 12 extending at a right angle relative to shaft 59.

Rotation is transmitted to the rollers 55 and 56 by the conical wheels 13 and 14. Endless press bands 63, 54' are supported on rollers 65, and 66, 66 The bearings 69 and H1 are displaceable on their supports 15 for the purpose of adjusting the tension of the press bands 53, 64. The upper band 63 is held under tension by the spring 8!. For this purpose, a plate Ti is located above casing 56; the plate is supported on levers F8. The levers it engage plate 11 by means of the rollers 89 and press it upward under the action of springs '8! connected to the machine frame by pins 82. Rollers M supporting the endless press band 63 are mounted on the upper portion of ribs 83 fastened to the machine frame.

The lower band 64 is conducted with its upper portion over the rollers 85 supported by the ribs 86 of the casing 56. The upper band 63 is pressed against the lower band 64 by a vertically adjustable plate 8'! provided at its underside with elastically supported rollers 38. The rollers are guided in pairs stepwise or staggered in U-shaped yokes, the bolts of the rollers moving in slots 90 of said yokes. A spring 9| engaging a bridge 92 and connecting the two bolts between the legs of the yoke presses the rollers downwardly (Figs. 3'and 4). The plate 81 is suspended on screw spindles 93, which are rotated by means of a handwheel 94 through the coaction of the conical wheels 95 and toothed wheels 56 to regulate the pressure of the springs 9!.

The bands are formed of pressing plates 91 exchangeably fastened on thin steel-bands 98 by means of screws 99. Any suitable number of steel bands may be used; in the illustrated embodiment four bands are provided. At the places where the plates touch each other, the steel bands are provided with cavities I00 extending into the plates 91; teeth I00 of the rollers 65, 65 and B6, 66 engage the cavities and carry the band along when rotated about their axes.

The stamping plates are heated by electric heating wires H12 embedded in grooves I03 and insulated by annular elements surrounding the wires.

The current is supplied by brushes or slide contacts I04, I04 supported by angularly shaped members I05 located at the ends of the plates, see Figs. 5-7. The contacts are bow-shaped and their ends are connected to the respective ends of two neighboring pieces I05 The contacts slip along current-tracks I06, I06 connected by electrically insulated means to supporting tracks I? fastened to the machine frame. To avoid an interruption of the heating current during the circulation of the band around the driving rollers a plurality of contacts (Fig. 1) is provided on the band so that at least one contact remains always in touch with the current tracks.

The heating wires of each stamping member end on the same side thereof and are connected to separate contacts I 0 3 and I04 respectively. Therefore, also the current tracks I06 and I06 are both located on the same side of the machine frame. I

If a plurality of bands 98 is used, the number and the arrangement of the rollers 85 and 8 8 acting on the upper and lower bands respectively correspond to the number and the arrangement of the bands.

The distance between two rollers 88 or 85 respectively is smaller than the width of a stamping member for equalizing the pressure along the whole stamping path.

The Figs. 8 to 10 show three pieces of upholstered paper ready for dispatch with three different patterns consisting of square patterns, diamond patterns, or hexagons, respectively. The components of the patterns have a linear shape, the lines being composed of successive individual points. Naturally any other configuration may be chosen, for these patterns.

As shown in Fig. 1, bus bar portions extend along the lower side of the endless member as well as along the upper side, but are interrupted near the sprocket wheels 65 and 65 As best shown in Figs. 5, 6 and '7, each of these portions is composed of a pair of bus bars, one for connection to a positive terminal and numbered I05, and one for a negative terminal and numbered lllt The individual bars of the pairs are situated one behind the other, so that in Fig. 1 only the front bus bar is visible of the lower portion as well as of the upper portion.

Two brushes are located on the upper endless band member 53, which brushes are both shown in contact with the lower bus bar portion, Fig. 1. As soon as the press is operated, one of the brushes, for instance, the one on the righthand side of Fig. 1, will interrupt its contact with the lower bus bar portion and travel first rightwardly and thence upwardly, until it makes contact with the upper bus bar portion; this subsequent contact is made before the other brush, shown on the left in Fig. 1, has also traveled beyond the end of the lower bus bar portion; by this arrangement one brush Will always be in contact with a bus bar portion The brush comprises two sliding contacts, namely the contact I04 sliding against the bus bar I06, and the contact I94 sliding on the bus bar I06 This is best illustrated in Figs. -7, and is also shown in Fig. 1, although in that latter view the pairing of the sliding contacts in each brush is less clearly perceptible owing to the small scale of the pictorialization.

' From this it will be apparent that, since the bus bars are always interconnected to an electric source, one of the brushes will always receive current; since one brush is always in contact with a bus bar pair of either the lower or the upper portion, a positive and negative sliding contact will at all times be interconnected to the respective terminals of an electric source to close a circuit.

Since, as shown in Figs. 5-7, all the pressing plates 9 are interconnected to each other, along a positive lead that is connected to the slide contact I04, and along a negative lead that is connected to the slide contact I04 all of the pressing plates 91 of the upper member will at all times be energized, irrespective of the position of the brushes along the bus bars and thus in all positions of the endless upper band 63.

In the operation of the stamping press moistened paper sheets provided with design forming gum spots are superposed as shown in Fig. 1 and conducted into the stamping press, Fig. l, which they leave as a single strip to be cut into individual sheets.

The invention enables the production of diversified patterns in the same machine and it is only necessary to provide the stamping members with the respective patterns, which are also applied to the gumming rollers, the latter applying the gum to the endless paper strips before they enter the stamping press. There will be practically no restriction with respect to the patterns. Nevertheless a strip-like or line-like operation will be preferred. To reduce the strip-like gumming to practice the stamped lines should suitably be interrupted.

Having thus particularly described the nature of the invention and the manner in which the same is to be performed what is to be covered b Letters Patent is:

1. In a machine for manufacturing upholstered paper which is composed of a plurality of superposed paper sheets, the latter being partly gummed and partly embossed with a continuous pattern comprising a machine frame, two superposed endless press plates supported by said frame, dash and point forming elevations located on adjacent surfaces of said superposed plates, an upper and a lower steel band supported in said frame, a supporting plate, vertically adjustably located in said frame, yokes fastened to said supporting plate, slots provided in said yokes, bolts having pressure rolls attached to their ends movably located in said slots, bridges bearing said bolts and springs provided between said supporting plate and said bridges to press the pressure rolls contacting the press plates connected to the upper steel band against the press plates connected to the lower steel band.
