Description

Autobond Multi 76 TPE-H-CC-S
(Thermal, Perfector, Edge-seal, Heidelberg, Cross Cutter-Stacker)

Laminator:
Maximum sheet size 29.5” wide x 41.73” long. Minimum Sheet size 11.5” x 12”. Maximum mechanical speed is 200 ft/min or 3600 28” x 40” SPH. Paper weight 80 lb text to 24 point board.

The laminator is of heavy-duty construction, using 7/8” inch thick steel side plates with 3.25” x 3.25” steel support beams. The rolls of film are mounted on two quick-change airshafts. A pneumatic clutch controls film tension. There are two sets of laminating rollers; the first, a highly polished 9.25” diameter chrome roller, and a 6” diameter rubber roller for application of thin films (<1.7 mil) one or two sides. These are pneumatically adjustable up to 6 metric tonnes on the nip. The second is comprised of a set of 2 x 2.5” diameter, soft durometer rubber rollers for running two sided edge-seal or flush cut thick film work. Running in this mode, thick film (1.7-10 mil) passes over two 9.25” diameter chrome pre-heat rollers before passing through the 2.5” diameter rubber nip rollers where lamination or encapsulation takes place. The chrome rollers are heated with 2 x sophisticated 12 kw Swiss made temperature control units (TCU’s). The TCU’s pump hot water into the rollers at a rate of 10.5 gal/min and immediately back for re-heating.

Feeder:
This is a rising pile, back separation stream feeder. The Heidelberg Speedmaster 102 feed head is driven by a servo motor, with forwarding suckers to feed the sheets. The sheets are fed down an angled feed table that is fitted with a micro-adjustable side-lay and up to mechanical front lays (head stops) before passing into the laminating rollers. The front lays dictate a precise gap between sheets when running thick film two sided work, pre-programmed using the HMI. The feed head is processor controlled. The feeder is fitted with a mill skid plate, allowing a full pallet of print to be loaded directly from the printing press.

Front Lays:
Situated in front of the nip roller, the front lays meet the leading edge of the sheet and register the leading edge relative to the trailing edge of the previous sheet, giving an accurate overlap to within +/- 1/32”. Front lays are a positive cam driven system controlled by a Lenze servo drive.

Perfector:
A printing term for two sides in one pass. The perfecting option consists of an extra film airshaft for mounting a bottom roll of film which then wraps around a preheat roller and the rubber roller, and chill rollers to cool the product prior to delivery. When a valve is opened, both the pre-heat and the rubber roller are heated with water from the TCU at a rate of 15 gallons/minute.

Bump Sheeter:
The Autobond bump sheeter runs in-line. Sheets are delivered into a vibrating jogger. Features include a digital sheet counter, an adjustable anti-curl bar, pneumatically adjustable in-feed nip rollers, and a pneumatic air clutch to give a constant tension between the laminator and the sheeter. There is a separate motor fitted to the bump rollers to independently vary their speed to assist with separation of nylon and PET films. Start/stop and speed up and down controls are also located on the laminator.

CC76 (29.5” wide flying knife cross cutter):
Situated behind the bump separator, the stand alone cross cutter runs at a top mechanical speed of 200 feet per minute with pinpoint accuracy for separation. The CC 76 is very advantageous for running PET and Nylon films ensuring a completely flat sheet. The accuracy of the cross cutter, which is driven by a servo motor on the in-feed and a servo motor on the cutter, allows for a single cut across the material in a transverse direction using an arrow head blade on thin film one sided applications. A return cut is made when the next sheet is detected by a laser detector registering the overlap in the sheets. Sheets are fed by the servo driven in feed rollers. Flat delivery of the sheets into the stacker is ensured. When running flush cut thick film or edge-seal work a space is left between the sheets and a gap detector activates the cutter head to make a cut with a disc blade. It is able to do two sided flush cut and edge- seal applications. The CC 76 is designed to handle up to 10 mil film. The cutter-head is designed to easily switch the blade when changing between different applications.

Stacker:
Sitting immediately behind the flying knife cross cutter, the Autobond Stacker fully automates the system. The system incorporates a delivery belt frame system which receives the incoming sheets, and holds them firmly in place as they travel towards the pile. Electronically stand-alone, the stacker uses a photo electric cell which detects the front of the incoming sheet, and opens four pneumatic joggers, while activating under sheet air blasts to float the sheet across the pile. The same photo electric cell detects the rear of the sheet and activates slow down drop wheels on the last inch of the sheet, while turning on rear down blowers on the tail end of the sheet and activating the joggers inwards. The milled skid plate continually lowers at automatic intervals until a full pile is neatly stacked from floor level up.

Electronics:
The machine is fitted with Lenze programmable logic controllers, which control all machine functions. All drives are digital AC inverter drives. Lenze products provide remote machine diagnostics using via Ethernet router, allowing Autobond technicians to provide real time assistance remotely. Electrics are 380-415 volt. Note: A transformer is required to either step up or step down customer voltage.

Additional Machinery Features:
Edge trim and rewind - There is an edge trim knife which removes excess film when running edge-seal application and edge trim rewind system to remove scrap film.
Cooling system - Compressed air cooling system and 12” diameter water chilled chill rollers cool the web prior to sheeting.
