Application July 20, 1934, Serial No.. @1363@ l Gleim. (6l. Miu-395i The present invention is a ilexible printing plate..
It is an object oi this invention to provide a printing plate of flexible material which may be utilized interchangeably on cylinder or letter presses and in fact any press of the rotary type or of the type which uses flat plates.
It is a further object ci the invention to provide a printing plate which may be used interlo changeably on cylinder presses of all types regardless of the size of the cylinders.
A further object of the invention is the provision oi a novel base or backing'for the plate, which base will not only provide a exible assembly, but will also furnish additional resiliency to the same, whereby objects of various thicknesses may be printed without adjusting the mechanism of the press.
Another object of the invention is to provide a printing plate which will be simple in construction and of low manufacturing cost, yet rugged and convenient in operation and use.
Other objects and advantages of the invention will be apparent from a reading of the following 26 description in connection with the drawing, wherein for the purpose of illustration, I have shown a preferred embodiment of the invention.
In the drawing: Figure 1 is a perspective view of a printing plate embodying myinvention,
Figure 2 is an enlarged sectional view taken substantially along line 2-2 of Figure l,
Figure 3 is a similar view, but showing the plate as applied to a cylinder press or the like,
Figure 4 is a plan view of a printing plate showing a modification of the invention, and
Figure 5 is a sectional view taken along line i-S oi' Figure 4.
Referring more particularly to the drawing. 4 there is shown therein a ilexible printing plate having a ilexibie printing surface l0, preferably formed of rubber, and a backing l l of flexible mateial secured thereto by either cement, or, pref erably, by vulcanization under great pressure, 5 whereupon the base and printing surface become integral for all practical Purposes In the preferred form of the invention, as disclosed in Figures l to 3, inclusive, the base ll is formed of a rather still yet iiexible material con-v sisting in this case ci a pair of outer sheets oi canvas or the like impregnated with bakelite or other condensation product of phenol or the like,1 as indicated at l@ and it and having integrally vulcanized therebetween a sheet of very pliable rubber as indicated at l5.
, This form of the invention allows the plate to be used readily upon letter presses because of its semi-rigid assembly, yet provides means for its use upon cylinder presses, also, if desired.
ln the embodiment oi the invention disclosed in Figures i and 5, the printing surface l@ is shown vulcanized to a preferably very heavy labric which permits oi the plate readily being used upon cylinder presses of all sizes, yet provides means for its use with @at type presses.
' Both forms of the invention may be secured to4 the soecalled patent blocks" or wooden backings zo by means of fastening devices -of conventional I character.
One of the advantages of this construction is its great adaptability to all types of presses and its capability of use, without ne adjustment, in 26 connections with materials of various surfacesv such as, for example, paper, cardboard, textiles, glass, fibre, sandpaper, aluminum products, tin, celluloid, cellophane, corrugated boxes, bakelite products, burlap, asbestos, metals, wallboard, oil 30 cloth, wood and other rough surfaces in one or more colors of ink or dye as used in the printing 'Though I have shown and described herein the preferred embodiments ofthe invention, it is to be denitely understood that I do not desire to limit the application of the invention thereto, but any change or changes may be made in the structure or arrangement within the spirit of the invention or the scope of the appended claims.
What is claimed is:
A printing plate formed of rubber and having a backing sheet formed of a pair of fabric sheets impregnated with a phenolic condensation product with a layer of soft rubber therebetween.
