TECHNICAL DATA FOR THE LINE
The Maxima Wr, automatic wire-o binding machine, was born for the calendar production; thanks to its mechanical speed (3000 cycles per hour) and its extreme easiness and speed in format changing, it allows the user to reach very high net productivities and, therefore, to be really competitive on the market.
The Maxima Wr is linkable only with last generation Maxima collators with computer, except for some cases which have to be individually considered.
The wire-o binding machine is electronically interfaced with the collator, so that when a variation is made on one of the two machines, the other is able to adapt on the first one. It has a touch screen panel, which, thanks to simple icons, allows to operate in a intuitive, fast and effective way also while the machine is working.
Maximum in a medium 300 x 500 mm. format 3.000 mechanical cycles/hour.
The actual production speed and the actual net output are dependent on size, paper quality, thickness, condition of stock and other operating conditions.
Max mm 500 (binding edge) x 800 - Min mm 120 (binding edge) x 120
Maximum perforating thickness (depending on the material) mm 3÷4
From 70 to 900 g/m2. - To process sets made of sheets with characteristics out of the above mentioned data it’s suggestible to ask the manufacturer for a previous test.

After the exit of the collator, the set enters in the wire-o binding machine where it finds three joggering stations, which register the material by means of three beating squares (head and foot and side).
The transport of the material in this section is made by means of pusher fingers, which simply push the calendar without drag it and avoiding to mark or make dirty the set.
CARDBOARD FEEDER (OPTIONAL)
In the first station it’s possible to feed automatically the “triangle” cardboard for the table calendars by means of a suction feeder: in this case the joggering stations are equipped with special squares to jogger the shorter sheets.
Once the material comes out from the joggering perfectly registered, it is blocked between two belts which, with a variable pressure, avoid any movement, assuring no scaling of the calendar. The material is punched by means of punching tools with 3:1” pitch (this choice has been made evaluating the market demand, which use for the 90% this solution, but it’s possible to have, on demand, also 4:1” pitch).
All the adjustments of the punching tools and matrix during the format changing operations, are extremely simple and reliable due to the fact that the machine works with a fixed zero point (on the right side): in this way it needs only to lean the first punching tool against the proper register square.
Once the adjustment has been effected, automatically will be also set upthe wire-o binding station.
WIRE-O BINDING STATION
After the punching the material comes over in the binding station. The wire-o is hanged up to the calendar without moving it. The passing between the punching and the wire-o binding stations is electronically synchronized and changes with the changing of the speed of the line. Also the speed of the wire-o hanging up is proportional to the machine speed and thanks to this the line is able to reach very high speed. This architecture allowed a high process reliability, thanks to the fact that is the wire-o that is brought to the calendar which doesn’t suffer any movement that can change its composition.
The binding station is hanged up on a interchangeable trolleys in order to make faster the wire-o diameter changing (1/4”, 3/16” and 5/16” diameter kits are available): when a change of a kit have to be made, with simple actions, the group is released from the machine and is replaced with the other one.
In this station there is also the metallic hanger forming and hanging up by means of a loader, which can contains more than 500 pre-cut 2 mm diameter wire straight pieces. The hangers, once they are formed, are stopped in a accumulator (it can contain about 70 hangers), which allows to the user to refill the loader without stopping the production.
The last station receives the calendar, which is diverted 90° on the left, compared with the direction of the material in the wire-o binding machine, on a delivery conveyor, where is checked the presence of the hanger by means of a sensor which stops the machine in case of missing hanger.
