press point-press guides

Gerald Lange refers to press points just less than type high locked up in the bottom of the form to preventpaper slurring on the type for cylinder proofing presses, and Richard Gabriel-Rummonds used point just above type high in the form to assist with registration on Mylar strips on hand press tympans. Well my mate Mick in UK has invented this mechanism , which can be locked up at either height in the chase or by quoin that does both of these functions-any comments are most welcome for this prototype to be developed further.

I have used traditional press points to prevent tail slur on forms which have images near the tail edge. They do work well and must be set just below roller height to prevent a dot of ink from showing on the sheet. I think if I were using a cylindrical format as shown, I would drill out a piece of furniture to house the cylinder. I don’t think you could effectively lock up a form aginst so small a pressure point.

Press points used in iron hand presses (in my experience) are quite different, and are attached to the tympan or tympan frame. The sheet is actually pushed onto the points so as to put a tiny hole in the sheet peing printed. This is generally positioned in the gutter between pages and must be centered to be at the point of fold. The sheet may be then replaced on the pins for a second color to be applied in register, or flipped to obtain registration from the front to the back of the sheet.

Interesting. How are these locked up? and held in position? How are they prevented from working up?

Does that little split canister have a floor to it? to allow for the differing heights.
