(GRANTED UNDER THE PROVISIONS THE ACT MARCH 8. 192341 STAT. L, 1313.)
T all 107mm 11/ may concem Be it known that l, Room liinmn'srnin, a citizen of the French Republic, residing at Paris, 83 Bd. llxelmans, have invented Improvemcnts in Apparatus for Eilectiug the Gripping, the Extraction, and the Folding of Sheets of: Paper Contained in a Maga zine (for which l have filed an application in France. July 16, 1920, Number 520,612), of which the ttollowing-isa description.
This invention has for its object to provide an apparatus enabling sheets ot paper contained in a magazine to be gripped, extracted and folded in asimple and effective manner. i i
In order to enable the invention to be un* derstood, it will be described with reference to the accompanying drawing which illustrates by way of example the apparatus according to the invention.
Figure 1, is a sectional elevation of the apparatus.
Figure 2, is a plan view partly in section, The same reference numerals designate the same parts in the two figures of the drawings.
The apparatus in question is adapted to act upon sheets ol paper of any size, weight and consistency, but especially upon sheets of thin paper, such as cigarette paper, which have been cut in advance in such a way as to present sheets of the desired width, and of a length which may be equal to the length which it is desired to obtain, or some multiple of this latter.
The apparatus is applicable in particular to cases where it is required to feed sheets to roughened rolls disposed in a known manner and serving to crimp paper for making up cigarettes, toilet sheets, for impressed prescriptions and so forth.
The apparatus consists essentially of two parallel cylinders 1 and 2 supported at each end by spindles 3 and 41. mounted in bearings at 5 and 6; the bearings of one of the cylinders may be adjustable for example by means of micrometer screws in such a way as to enable the pressure of the cylinders one against the other to be increased or reduced as may be required. The cylinders are driven by means of suitable gearing 4i, at, driving the spindle 4 for example and actuated from an engine shaft, while the two cylinders are geared together by pinions 11 and 12 of equal size.
The exterior surface of the cylinders is smooth but is provided along one or more longitudinal strips with a gripping surface *Sf ---"i"ii'i l, o a com eniene w icti, acapted to effect by l'rictional action the gripping an clthe extraction of the sheets of paper, as will be described below. The cylindersin question may, for the rest, be co neredv with a suitable plastic covering material (leather, compressed paste-board, rubber and so forth) in the space comprised between'two parallel lines in the neighbourhood of the gripping surfaces? and 8 referred to above, and in the parts at 9 and 10 of the cylinders which insure the formation of the fold.
The cylinders 1 and 2 are driven in the direction indicated by the arrows f 7, re i spectively by means of the gearing already described. i
Above the cylinders is disposed a magazine 13 containing the sheets of paper which are to be extracted and folded, The bottom "14 of this magazine is placed at a short distance, from the tangent plane common to the two cylinders 1 and 2.
The gripping surfaces of the cylind ers dur ing the rotation of these latter pass through an aperture at 15 in the bottom 14 ot the magazine and they engage trictionally the sheet of paper at the bottom of the pile of sheets P contained in the magazine. The bottom sheet seized in this way is caused to form a loop at the middle between the two cylinders, and this becomes converted into a fold or crease when the sheet passes through the line of contact atl6 between the cylinders.
The folded sheet of paper subsequently becomes released by the cylinders as they continue their rotation and falls in the direction indicated by thearrow 9, into a receiving magazine or any suitable receptacle, accordingto the ultimate destination of the sheets of paper, (tor example into the feeding aperture of the crimping rolls in the case where the apparatus is applied to sheets of paper intended for automatic distribution as crimped sheets). v v
The apparatus constructed as described above operates without the necessity of employing an air exhausting machine and without the comparatively complex and delicate devices which are necessary in other ma chines of this character for insuring the seizing and the extraction of the sheets by the adherence of these sheets to the surface of the cylinders, such adherence being in those cases obtained solely by means of suction created in the interior of cylinders which are hollow and provided with rows of holes along one or more longitudinal lines.
However, in order to insure regularity in the operation of the apparatus according to this invention, and to render it independent of the amount of paper contained in the magazine, or of the greater or lesser degr'ee of glazing of the surface of the paper, I may combine the action of engagement by means of suction through holes in the hollow cylinders.
In this case, the apparatus above described is combined wit-h an apparatus similar to that set forth in the specification of my copending patent application of even date entitled Improvements in apparatus for effecting the extraction successively of sheets of paper contained in a magazine, and for folding such sheets. In that apparatus hollow cylinders are used with longitudinal perforations in rows thereon, and the cylinders are connected through trunnions with a box adapted to be connected alternately to suction or opened to the atmosphere as the cylinders rotate.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I, claim is:
The combination with a magazine for holding sheets of thin paper in a pile and having an opening in its bottom, of means for gripping said sheets one by one and extracting them through said opening and folding them, comprising two parallel, cylinders 1,2 arranged directly beneath said opening, said cylinders being provided in their surfaces with narrow strips 7, 8 of friction material extending longitudinally of said cylinders, said cylinders being further provided adjacent said strips 7, 8 with narrow strips 9, 10 of plastic material, said cylinders being geared together in such manner that when they are driven with their upper surfaces turning toward each other, said strips 7, 8 will simultaneously frictionally engage through said opening the bottom surface of the bottom sheet in said magazine and in extracting it through sald openlng give it a buckle which is then gripped by the plastic strips 9, 10 to complete the folding.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
