Abstract
The invention relates to a pressing apparatus with multi-platen or tiered presses which has a charging basket 1 capable of receiving more tools with material to be pressed than there are tiers in the presses H, K. The capacity of the discharging basket 2 exceeds that of the charging basket 1 by the number of tiers in the tiered presses H, K. The charging basket 1 and the discharging basket 2 are vertically adjustable. The invention makes it possible to stock several tools in the charging basket 1. The tools can then pass through the presses to the discharging basket 2 automatically.
Claims13
A pressing apparatus for the manufacture of multilayer printed circuit boards, comprising:
- a multitiered heating press and a multitiered cooling press;
- a loading and an unloading facility for transferring tools, with a pressing material contained therebetween, through the pressing apparatus;
- a vertically displaceable charging basket having an upper edge and a plurality of shelves equally spaced from each other and whose number is equal to an integer multiple of at least two times the number of tiers in said multitiered heating press, said vertically displaceable charging basket being disposed in said loading facility and having the ability to be lowered so far that its upper edge lies under the lowermost tier of said multitiered heating press;
- and
- a horizontally movable vertical feeding arm also disposed in said loading facility and having a plurality of horizontal push rods corresponding in number to the number of tiers in said multitiered presses so as to provide for a synchronous insertion of the tools from the charging basket into all of the tiers of said multitiered heating press and said multitiered cooling press alternately.
