In the form illustrated in Figs. 3 and 4, I have shown inking mechanisms H3, H4 mounted in a frame H5 in position to be brought into and out of coaction with either the two larger change form cylinders 2|, 22 or the two smaller change form cylinders 25, 26.
The web to be printed is denoted by I I6 and the impression web is denoted by M1. Any well known or approved means, not shown herein, may be provided for imparting the proper movements to the web to be printed and the impression web. Any well known or approved means may also be provided for driving the impression and change form rolls as well as the inking mechanisms.
The impression web shown and described, but not claimed herein, forms the subject matter of my copending application filed of even date herewith, Serial No. 343.
While I have shown change form cylinders of two corresponding diameters it is to be understood that these change form cylinders may be of any desired diameter.
From the above description it will be seen that in both forms illustrated I have provided means whereby a selected change formcylinder upon one side of the impression cylinder may be moved independently thereof. In the form shown in Figs. 1 and 2 the impression cylinder may not only be moved together with its change form cylinder on the other side thereof but said change form cylinder may be moved independently of the impression cylinder. In the form shown in Figs. 3 and 4 the two change form cylinders may not only be moved with the impression cylinder but also independently thereof and independently of each other.
It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiments herein shown and described, but what I claim is: V a
