PROPHETEER MID-WEB PRESSES 23" TO 32"
Narrow web efficiency in a mid-web press. Built with the same operator friendly design philosophy as our narrow web presses, the mid-web press features a walk-in print station that gives the operator total access to the print head. STANDARD FEATURES UNWIND
Roll Lift - maximum roll capacity is 40 inches diameter, 24 inches wide weighing 1,276 pounds
Coreholder- three inch diameter air expanded, with inflator included.
Roll End Detector - the follower arm is easily adjusted to minimize waste when using cores of varying thickness.
Unwind Dancer - regulates the roll tension brake and smoothes out tension variation caused by an out-of-round roll.
Splice Table - pneumatic clamps and a cutting surface with a built-in straight edge and adhesive tape roll holder facilitates accurate and quick splicing.
Unwind Tension System - a high friction roller connected to a magnetic brake creates web tension. A transducer roll located downstream from the tension drum measures the amount of tension in the web, feeding that information to the tension controller, which in turn controls the magnetic brake. The tension controller features convenient setting buttons and numeric display of set point and running tension.
Edge Guide - an electronic edge guide precisely controls the web position.
Control panel functions include push buttons for Jog, Stop and Emergency Stop (which remains engaged when activated). Controls for the roll lift and brake, splice table clamps, web tension and web guide are conveniently located.PRINTING
- Maximum printing width is 23 to 32 inches.
- Plate cylinder circumferences range from 12 to 26 inches.
- Drying is by high velocity gas-fired hot air, with thermostatic temperature control up to 300°F; supply and exhaust blowers provided.
- Lineal (web direction) running registration adjustment is motorized 360°.
- Lateral (across the web) running registration adjustment is 3/8 inch.
- Light weight ceramic anilox roll, 65 durometer meter roll and doctor blade, an enclosed doctor blade system and ink pump are included.
- Idling drive for the anilox roll and metering roll engages when the press stops.
- Inking system contact with the plate cylinder is thrown off when the press stops.
- Impression rolls are through-hardened precision ground tool steel, treated for corrosion resistance.
- The inking system can be skewed to achieve perfect alignment to the printing plate, and to compensate for any inconsistency in plate or stickyback material.
- Walk-in design provides maximum operator access to printing adjustments.
- Swing-away dryer for easy access to the webbing path.DIECUTTING
Two diecutting stations are standard:
- Maximum die circumference is 26 inches.
- Minimum die circumference capability is 12" for top side diecutting and 18" for bottom side diecutting.
- Motorized 360 degree lineal registration adjustment.
- Removable through-hardened precision ground tool steel base rolls in each station.
- Lower base rolls provide support and stability for the removable base rolls.
- Die pressure hardware is quickly and easily removed and installed to expedite die change.
- Bearer and bearing oil wipers.
- 1-1/2 inch thick steel frames.WASTE MATRIX REWIND
- single 39" diameter rewind capacity.
- 3" pneumatic coreholder with inflate/deflate switch.
- adjustable tension capstan rollSLITTING AND PULL ROLL
- Three laterally adjustable air operated slitters, with a through hardened and ground tool steel base roll.
- Pneumatic adjustment of pull roll pressure.
- Pull roll can be removed for cleaning.SHEETING
One sheeting station provided:
- Maximum die circumference is 26 inches.
- Minimum die circumference capability is 12" for top side and 18" for bottom side diecutting. *
- Motorized 360 degree lineal registration adjustment.
- Removable through-hardened precision ground tool steel base roll.
- Lower base roll provides support and stability for the removable base roll.
- Die pressure hardware is quickly and easily removed and installed to expedite die change.
- Bearer and bearing oil wipers.
- 1-1/2 inch thick steel frames.REWIND
- One 40" diameter capacity rewind with roll unloader.
- 10hp AC motor driven shaft with automatic taper tension control.
OPTIONSUNWIND
Driven infeed - A constant ratio driven infeed upgrade.
Corona treater - Elevates surface energy of film materials to improve ink adhesion.
Larger diameter roll capacity - 60"and 72" unwind roll stands with integral hoists or automatic roll splicers up to 72" diameter.
Multiple unwinds - For multiple web products.
Web cleaner - Various systems; one or two-sides, rotary brush or non-contact, and static eliminator bars.PRINTING
Adhesive print kit - Separate the liner and facestock of P.S. material for the purpose of printing on the adhesive side of the facestock, then relaminate the two webs together (also called delam-relam).
Automatic registration control system - An electronic system monitors and controls printing registration.
Ceramic anilox roll - Additional anilox rolls with other cell counts and volumes may be specified.
Diecutter - A diecutting module can be located between any press stations.
Lightweight meter roll - A reduced weight metering roll is available.
Ink pump - Air-operated centrifugal or electric peristaltic ink pumps.
Reverse print kit - Printing on the bottom side of the web can be done without the use of a turn bar by reversing the rotational direction of the print station.
Turn bar - Used to flip a web over; compressed air required.
UV curing - UV lamps of various power are available, with manual or automatic speed-tracking power supply. Infrared (IR) cut filters also available for heat control. An exhaust blower is included.DIECUTTING
Additional die station - A modular die station can be added.
Additional waste rewind - Add a second 39" diameter waste rewind for piggyback material stripping or for laminating release film rewinding.
Lamination unwind - Pneumatic-controlled brake on cantilevered shaft unrolls laminating film. Laminating film with release liner requires a waste matrix rewind to rewind the liner.
Lateral die adjust - Provides 3/8" side-to-side running adjustment of the die for alignment to the printed web.
Linehole punching - A punching module can be added on a diecutting base.
Shear cut slitting - Replaces the standard crush cut slitters.
Waste break detector - Optical sensor monitors the waste matrix and stops the press if the matrix breaks.DELIVERY
Batch counter - Counts and separates batches of product.
Folder - B. Bunch folder and drive connection to the press.
Stacker - Two models are available; a stacker for forms and labels and a de-nesting stacker to separate nested diecut cartons.
Rewind Diameter - 50" and 60" diameter rewinds are available, as are 6" and 12" coreshafts.ACCESSORIES
Strobe light - Strobe lighting provides web viewing at production speed - commonly used to check printing registration targets.
Video Plate Mounter - Plate mounter with video cameras to magnify alignment marks 20 times for high mounting accuracy.
Web break detectors - Optical sensors monitor the web at several points throughout the press. A display panel identifies the location of a web break in multiple web break sensor installations.
Video web viewing system - Video camera-based system with high quality monitor for web inspection at production speed. Used for checking print quality and registration.
