perfecting press speed

[joe stag]

Is it ok to run a heidelberg xl-75 at max speed while in perfecting?

I always understood there is a straight line top speed and a perfecting top speed which is usually a couple of thousands sheets per hour less. I would think it is ok to run a press at the top speed specified in the machine specs for perfecting as long as the press has been maintained in good condition mechanically.

I have been told by a few different heidelberg techs that there is no danger of damage to the press running at full speed in perfecting. 1 as long as it is maintained well (i do my own maintenance and can vouch that it is) 2 pincer bar play is at min. (Perfector cylinder was just rebuilt by heidelberg mechanics due to water damage). 3 press will only run at 15 iph and was told by 3 different techs that "if it only allows 15k iph then it is designed to run at 20k iph).

It's OK to run at top speeds as long as your press condition and substrate allows.

Thank you both for your replies. I have put months and months of frustration, research, and trial and error into this piece of s#<t that they bought. I was only given 2 weeks of training from a demonstrator. Now that i have finally fixed the mechanical errors and done my best to eliminate the human error part of it, yesterday i walked out because apparently now i run to fast. Just trying to prove a point here. Anyone looking for a press operator?
