The Auto Lap Unwind consists of two standard stacked RG unwinds with individual Vector drives and dancer tension control. An infeed drive and web reference roller control the festoon motion while a common splicing station cuts and nips the web from one roll to the other. A central controller monitors roll size, web speed, web caliper, festoon and dancer positions as well as operator settings for auto roll stop and web tension. This information is provided to the operator in a touch screen at the operator control panel. The unwind is described in three groups; the unwinds, the splicer, and the festoon. Auto Clamps: The shafts are held in place with an automatic shaft clamp that is pnuematicly operated and cams over for a fail safe lock. The air cylinders are built with a magnetic pick up for feedback to the PLC. Sidelay: The unwind motor is mounted on a sub frame assembley that rides on three linear bearings for 4” of total sidelay travel. The frame is moved with a screw through a hollow shaft gearbox. The sidelay feature is available with a manual handle, electric slo-syn motor, or servo motor positioning. Dancer: The unwind tension from the feed station to the master roll is controlled with air pressure on the dancer air cylinders. Two air cylinders are fed 0-90 psi air from an electro pneumatic valve. The dancer air pressure is selected in the touch screen and modified during splicing to reduce web breaks. Pass through festoon: The 15 roller festoon accumulates aproxamatly 120’ of web in a stacked three pass design. When the festoon is in the lowest position limit the carriage idlers pass through the fixed idlers to allow the web to be passed through the gaps and sew it’s self up once the carriage is lifted.

Each model of Turret rewind features our long pressure arm with integrated taper tension and optional slitting. The pressure arm design provides a simple path for webbing and a compact splicing unit. The simple design and intelligent control produce a turret capable of very precise control of tension and roll quality. Two AC Vector drive powers the rewind stand for accurate roll speed and web tension. Rewind stand are located in a cabinet with touch screen interface for the operator. An Air Actuated Nip Roll with pressure control is standard on the rewind stand to eliminate air trapped in the rewound roll and ensure tightly wound rolls. A bowed roller will be incorporated to aid in slitting delicate substrates. The stand comes equipped with two three inches in diameter, air locking shaft. Stand is equipped with locking shaft clamps for rapid roll change. Roll size 10” to 40” Tool less female slitter knife removal. All safety areas gated or covered by hard mounted guards. Both manual and automatic operation. Dancer tension control set in touch screen. A dancer assembly will control tension.

The patcher can place windows on envelopes, boxes or run a continuous stream laminated to a web. The customer will specify 10DP or 14CP for the patch drum repeat. Touch screen Operation, setup and cleaning of the glue station and knife station. Patch length and bag length Speed settings for automatic startup Vacuum and blower functions General operation status and control. Status page for fault records and servo status. Glue applicator The glue application unit has independent plate to Anilox and plate to impression adjustment. The glue applicator is equipped with a doctor blade chamber system. A drip pan is located directly below the doctor blade chamber system. Pumps are available in both peristaltic or diaphragm. Quick change of plate and Anilox cylinder without any use of tools. All rollers are supplied with optimal bearing seals to prevent glue integration. {RG engineering Inc. :: Patcher RG engineering Inc. :: Patcher RG engineering Inc. :: Patcher Belt Delivery The vacuum belt drive is supplied with a separate servomotor linked to the glue unit. The vacuum belt is a seamless belt with bushings designed to allow quick change. Rotary cut off The Knife and Anvil Rollers are driven by independent servos for allowing consistent accurate cuts. Patch application The impression roller is located under the patcher's Anvil cylinder, and is sleeved for easy in machine replacement. The patch applicator can be laterally adjusted via a turn wheel and acme screw system.

An AC Vector drive powers the rewind stand for accurate roll speed. A twin roll dancer will control web tension in the rewind stand. The unwind is linked to the press via RG encoder and a central controller for high speed, accurate web tension control. A digital readout counter gives the operator the following recordable data: Totalizer (total daily output) Footage count An Air Actuated Nip Roll is standard on the rewind stand to eliminate air trapped in the rewound roll and ensure tightly wound rolls. A spiral grooved spreading roll will be incorporated to aid in rewinding substrates. B uilt on two inch thick side frames with five structural cross members. Hydraulic Lift Out System

Each pump is computer controlled and linked to the press so they ramp up and down with the press speed supplying the required flow based on speed. Designed to reduce flashing in anilox cells by keeping the roller wet at all times using twin pumps to feed and return ink to the doctor blade cavity. The tower will handle two print stations All lines use quick release fittings allowing the operator to remove for cleaning or color change. The system takes five minutes to flush the cavity and clean anilox roller though multiple stations can be placed in to clean mode at the same time making for rapid job or color changing.
