Press crew size for a modern high speed wide web press

Postby Ramee » Tue Aug 07, 2018 7:00 am

Normally how many workers are assigned to a modern high speed wide web press like a Bobst 20SIX. What would be the optimal amount of workers needed to efficiently run a press like that about 250m/min including printers and press assistants ?

one part of a fork truck driver to deliver substrate and remove printed substrate
a small part of an ink tech
one printer
one assistant
a little bit of a QC tech and a small part of a supervisor

if your fork truck driver, ink tech qc guy or girl and supervisor could be rolled into one, I would suggest the answer is about 3 people.

Hi
Is it a quick change over press?
How long are your average set ups ?Time from finishing last roll of a job to signing of the next job to start production.
How long does an average roll take to run through the press?

Cheers

Hi,
Yes it is a quick changeover press with sleeves for mounting plates, German made BOBST 20SIX wide web press. Machine runs both surface and reverse print jobs frequently. with different types of inks for lamination jobs, perforation jobs and normal surface printed jobs. Setup time is normally 1 1/2 hours to 2 hours bu if changing from 8 color surface to 8 color reverse is typically takes more time.

Now we are running some jobs (issue wrapping packaging ) that require slitting, wrapping and staking rolls standing up on to a pallet and rolls coming out at rewinder in every 12 to 14 mins. Unwinder rolls last about 45 mins normally.

Uh... :?:

… does it have to be just part of an ink tech? Do you recommend a specific cut of ink tech? :?
one printer

Okay, I can deal with this.

Okay, now that's just too far! :!:

Is this a pressroom you're talking about, or Frankestein's lab???

Sorry, it's been one of those days and I couldn't resist the temptation! :smile:

We have a Comexi F2 MB, average speed is also 250m/min and our crew is 3 + me.

One operator, one mounter, one assistant and me an ink tech/supervisor.

Mounter does everything around the plates (preparing, mounting, washing and archiving) and when there's time cleans around the machine.
Operator and assistant are preparing the machine setup as wells as preparing the material.

Once or twice a year we have a massive job which runs 350-400 m/min and requires immediate packaging straight from the press (rolls are ready approx each 10 minutes).
At that job we have 4 or 5 people to run it smoothly. Operator and assistant by the press and two or three guys at the back - for removing the rolls, preparing a new core, weighing, wrapping and storing it at the pallets.

Is it quick change type press? Can change sleeves and aniloxes while running?

Need one operator, 2 helper,s ink tech.

During set up, 2 guys working on sleeves, aniloxes, another guy on ink and chambers, and another on rolls, then this guy goes to assisting on clean up

It is quick changeover type press with automatic registration, wash up and and sleeve mounted plates etc. but can't change sleeves and aniloxes while running as all the access doors are locked while running. Thanks for the information! We are here in Australia trying to run this hi speed press with one printer and one assistant duo 12 hours rotating shifts 24 hours and it proving to be difficult in long run. Specially when running small rolls (3500 meters) that involves slitting, wrapping and staking on to the pallet and send direct to customer.

On small jobs, the operator only watches the print... One handles inks, one handles rest.. If needed add more to help slitting
