J. F. Looked at 2 M/c,s since the post, Black Ball from a long time ago, + One of the Last/Latest Red Ball, M/c,s (long time span in the production run.!) in both cases no extra/additional fittings or Mods.
Just spoke with long standing H/berg Platen Engineer/ Specialist, His best guess, possibly (for that is all it is) Precision drilled and rebated/countersunk holes, for attachement of special purpose extra fittings for Feeding 2 up piles, (well documented for the H/berg).
His theory was, (but again only that) when feeding 2 up, as both column,s have to be gripped all the way through, so second auxiliary lay edge is desirable.! Again guesswork.!
Variation of H/berg Cylinder,s 2 up Feed system whereby feed board, side lays, into the grippers are double sided & working in tandem. Only guess work.?? For the Platen.
Here in the past we have utilised the same kind of Modification (albeit in different format) on a Thompson Platen, which does not posses the 2 up feed option.
The job in question was to hole punch, and diecut, Book Marks, pre-printed but cut down to 12” x 2”. Had to be fed landscape, via the sucker bar. ***Footnote***
The feed & delivery tables are Aluminium, (on the Thompson) Non Ferrous, (magnetic Quoins not an option,) so Drilling & Tapping worked,. for outrigger extra lay guide. = pen steel, aux. finger.
Feed table probably, industrial *Laquer* to prohibit sweating, overnight in/with temperature/humidity variations.
Here U.K. indraughty garages quite common, as is slightly oily cloth draped over the Ink Cylinder and ink Train, overnight etc, + the wax paper/oiled paper, to protect the exposed ink, left in the ink duct.for any length of time, OR the expensive anti dry-on, spray.???
****The Thompson employs a different system to the H/berg, in that the pick up from the feed pile, is via the Sucker bar, straight in, down the Platen onto the Lay,s (only), but then gripped out, to the delivery pile.
5 gripper fingers, out, one just low enough to grip 2” landscape stock.!!
Horses for courses, of course, The Thompson, Can NOT *Bleed* on Lays, but CAN, feed Air Mail, Bible Paper, Tissue. Onion Skin, stock etc, streets ahead of Heidelberg *WINDMILLS*
Apologies for the ramble, but just one odd snippet may be of use.?
Because nails wouldn’t hold…
Kidding!
No idea, but are they in threaded holes, or are there nuts on the underside? Seems a custom fixture may have been attached.
Only seen the picture, I will see the press in person on Wednesday. I’ll let you know what I find out.
I might be mistaken - seems it’s kind of transparent plastic on the table.
