Abstract
Abstract A compound printer having print stations, die cutting stations and other operations, such as perforating and punching, has structure for rapid changeover of the individual stations. Movable carriages on carriage bars and indexing mounts allow rapid removal and installation of the elements, such as the print station or the die. Changeover time is substantially reduced. Removed components may be stored on the carriages.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
222 words
In a station of a compound printer for processing a continuous web, the station having a frame and at least one cylinder mounted within said frame; means for rapid changeover of said cylinder, said rapid changeover means comprising: bearing means mounting said cylinder within said frame for sliding transverse movement of said bearing means and cylinder in a direction parallel to the cylinder axis along a first track means, a cart having a main frame, bearing means supporting a replacement cylinder within said cart main frame for sliding transverse movement of said replacement cylinder in a direction parallel to the replacement cylinder axis along a second track means, said cart having a third track means for slidingly receiving said station cylinder, means for positioning said cart adjacent said station with said second track means parallel to said first track means and with said first and third track means in transverse alignment for the transverse sliding movement of said cylinder and its bearings from said first track means of said station and onto said third track means of said cart, and means for positioning said second track means in transverse alignment with said first track means for transverse sliding movement of said replacement cylinder and its bearings from said second track means of said cart onto said first track means of said station.

Dependent Claim
222 words
In a station of a compound printer for processing a continuous web, the station having a frame and at least one cylinder mounted within said frame; means for rapid changeover of said cylinder, said rapid changeover means comprising: bearing means mounting said cylinder within said frame for sliding transverse movement of said bearing means and cylinder in a direction parallel to the cylinder axis along a first track means, a cart having a main frame, bearing means supporting a replacement cylinder within said cart main frame for sliding transverse movement of said replacement cylinder in a direction parallel to the replacement cylinder axis along a second track means, said cart having a third track means for slidingly receiving said station cylinder, means for positioning said cart adjacent said station with said second track means parallel to said first track means and with said first and third track means in transverse alignment for the transverse sliding movement of said cylinder and its bearings from said first track means of said station and onto said third track means of said cart, and means for positioning said second track means in transverse alignment with said first track means for transverse sliding movement of said replacement cylinder and its bearings from said second track means of said cart onto said first track means of said station.
Claim 3
Dependent Claim
28 words
The rapid changeover means of claim 1 wherein the track means are sets of parallel rods and the bearing means have means to receive the parallel rods therein.
Claim 4
Dependent Claim
35 words
The rapid changeover means of claim 1 wherein said positioning means for positioning said second track means further comprise means for positioning said second and third track means relative the main frame of said cart.
Claim 5
Dependent Claim
39 words
The rapid changeover means of claim 3 wherein said cart further comprises a subframe, and means for adjusting the subframe relative said main frame, said second and third track means being mounted on said subframe in spaced parallel relation.
Claim 6
Dependent Claim
27 words
The rapid changeover means of claim 4 wherein said second and third track means are spaced apart vertically, and said subframe adjusts vertically relative said main frame.
Claim 7
Dependent Claim
29 words
The rapid changeover means of claim 1 wherein said main frame of said cart is mounted on rails for sliding movement of said cart for positioning adjacent said station.
Claim 8
Dependent Claim
18 words
The rapid changeover means of claim 1 wherein said station cylinder and replacement cylinder are die cutting cylinders.
Claim 9
Dependent Claim
27 words
The rapid changeover means of claim 1 further comprising means to fix the locations of said bearing means of said station cylinder on the first track means.
Claim 10
Dependent Claim
35 words
The rapid changeover means of claim 8 wherein the means to fix the location of the bearing means is a clamp means to tighten a portion of a bearing means against the first track means.
Claim 11
Dependent Claim
29 words
The rapid changeover means of claim 1 further comprising roller bearing means supporting the weight of said cylinders and bearing means for rolling engagement with said first track means.
Claim 12
Dependent Claim
33 words
The rapid changeover means of claim 1 wherein the station has means to urge the station cylinder into contact with said web, and means to rapidly retract said station cylinder from said contact.
Claim 13
Dependent Claim
31 words
The rapid changeover means of claim 11 wherein the urging means comprises means to adjustably vary the position of said urging means in a direction parallel to the station cylinder axis.
Claim 14
Dependent Claim
28 words
The rapid changeover means of claim 1 further comprising means for mounting said first track means for adjustment within said station frame toward and away from said web.
Claim 15
Dependent Claim
27 words
The rapid changeover means of claim 13 further comprising means for mounting said urging means within said station frame for adjusting toward and away from said cylinders.
