(Cl. 80-43) This invention relates to a method and appaplates it is known already to employ a wedge for ratus for introducing superposed plates of soft exerting pressure upon the plates vertically to and harder material into a rolling mill prior to their surface prior to feeding them into the rolluniting them by rolling. ers, but this device is unsuited for plating mills.

5 When plates made of a soft material, such as Evenif the wedge should be temporarily adjustaluminum, are to be united by rolling with plates able to slight pressure, the latter is not resilient, made of harder metals, considerable diillculties which, however, is absolutely necessary if sheets arise owing to the fact that the diiferent metals, of different degrees of hardness and extensibility .on account of their unequal extensibility, tend to are to be rolled together, for otherwise the softer be vertically or laterally displaced when introplates will be torn or at least deformed.

Therefore, plated It is further known to arrange yieldingly disrolled material of this class hitherto contained posed rollers in front of the main rollers, but defective portions, i. e., parts not covered by soft these rollers were hitherto intended for shaping material, which involved considerable waste, since and, for this purpose, pressed against the work only the perfect parts could be cut out and used. at regular intervals, while the yieldingly disposed 79 The invention proposes to eliminate these rollers according to the invention merely exert drawbacks by providing yieldingly disposed guide permanent slight pressure upon the plates to be rollers having lateral collars or flanges to prevent rolled in a direction perpendicular to their surlater'al displacement of the pile of hard and soft faces.
