Feeder
The latest Sanwa high performance Non-Stop feeder is particularly robust and extremely versatile. It can handle sheets of most qualities from 70gms paper, through 0.1 - 1.5mm solid board and up to B Flute corrugated without the need for extra equipment and with minimal set up alterations between the changing of materials. Pile height can be 1110mm when feeding non-stop or 1550mm when the non-stop system is not used. The feeder incorporates an overpile detector and a two-sheet detector. Loading can be either from the side or from the front. The non-stop feed method, in which the remainder of the previous pile is supported by hand inserted rods while the new pile is loaded, enables production to continue without interruption. The pre loader stacks can be placed on a trolley which is then wheeled into the feeder, and the fully automatic non-stop handles all further operations. As the feeder runs low on stock an acoustic alarm warns the operator. The speed of the pile lifting mechanism can be varied to suit the different thicknesses of paper, while the lowering action is always carried out at fast speed.

The lifting suckers which remove the top sheet from the pile and transfer it to the feed table are adjustable to cover various sheet thicknesses. The lifting suckers are telescopically mounted to allow ideal contact of each sucker with the top sheet and ensure clean pick up and regular in feed. A colour coded Pre-Alignment System is fitted and a further manual control for centralising the pile board.

Feed Table
The sheets are conveyed on moving belts along the feed table to the lays, and the stream is controlled from above by a variety of different devices which are installed as necessary according to the type of paper or board being processed. A synchronizing mechanism, which is adjustable by means of a handwheel without stopping the machine, matches the operating cycle of the feeder to that of the platen. The arrival of the sheets against the front lays can be advanced or retarded as required, so as to obtain accurate insertion into the grippers whatever the quality of the board being processed. The front lays are spaced to suit the sheet size by means of a single handwheel and positioned in the flow direction so as to match the printing press lays. At each registering cycle dust-insensitive inductive devices detect any sheet which contacts only one lay instead of both simultaneously, stopping the machine if any sheet fails to square up to the lays. The sidelays on both sides can each push or pull if required and are either used or left idle according to the way the printing press is working. The lays can be set over a distance of 12mm by means of a single handwheel. Any double sheets are also detected at this point by a device incorporated in the side lay, which stops the machine to allow these sheets to be removed from the feed table. The side lays automatically monitor the presence and accurate positioning of the sheet at each registering cycle.

Sheet Transportation
With Sanwa's designed 210 degree paper feed the sheets are clamped in the grippers by their front edge and are not released until they reach delivery. The "bottom" design of the grippers ensures that the sheets remain flat and at a constant level throughout all stages of the process. Transport Chains The transport chains are specially manufactured to meet the high requirement of our machines. In spite of high speeds these chains are remarkably quiet in action and they show negligible wear over long periods of use. The chain drive wheels are connected to the power transmission through an index unit, to protect the mechanical system from damage if the gripper bars are suddenly stopped for any reason. If the chains shift out of timing the machine stops immediately and they can easily be repositioned. The chain is also lubricated automatically by metered oil feed.

Platen Press
The press is extremely robust, and develops a pressure of 300 ton. The upper platen is fixed and the lower platen is driven up and down by a toggle motion. The 4 toggle levers act on the platen at points lying within the die-cutting format, ensuring uniform pressure distribution across the whole useful surface of the platen. The toggle motion, which was used in the very first Sanwa machines, generates more cutting force than any other system and gives the following advantages:  No vibration transmitted to the floor because the relatively slight dynamic load acts in the vertical plane only, from top to bottom  Only shallow foundations are necessary, giving considerable installation cost savings.  No mechanical clearances in lower platen due to toggle system.  During the cutting phase the two platens remain parallel at all pressures and speeds, so the cutting rules can be set to work with a progressive action, avoiding premature wear.  Make ready reconditioning is only rarely necessary. The cutting force can be adjusted easily and quickly by means of a handwheel, regardless of whether the machine is running or stationery. The value of the cutting force is indicated by a dial gauge incorporating a safety device which stops the machine in case of overload. All platen operating mechanisms are lubricated permanently by a central system pressurized by an oil pump with a filter allowing cleaning without switching off the machine. The cutting equipment slides out of the machine onto a pair of support arms, and can then be pivoted through 180 degree to allow convenient working on both top and bottom sides for any necessary adjustments. Efficient centering and locking devices locate the equipment accurately. All equipment is fully interchangeable between machines of the same type.

Diecutting Equipment
The upper chases supplied with the machine are accurately machined and are stiffened by a steel bottom plate. They can receive cutting formes of any size within the format. A centre line notch allows exact positioning of the cutting forme. For short set up times of repeat work, a thin plate system is supplied as standard.

Waste Stripping Section
The stripping mechanism which automatically removes all but grip edge waste of any size or shape works with a pinching action. The stripping tools are fixed into a honeycomb frame on the upper section and a pull out frame with adjustable bars in the lower frame. The pull out frames can also be prepared off-machine on a special make-ready table after which it is easily inserted and locked in position ready for work. Small or medium size sheets can be supported during their travel from the platen to the stripper by an apron to prevent them coming apart accidentally.

Delivery
The sheets are stacked neatly and reliably on pallets at all production speeds. The delivery is open on two sides, allowing easy removal of the pallet even in confined spaces. The sheets are slowed down by a brush and air curtain which keeps the sheets flat. The joggers can be adjusted for any format, and act on four sides. The back and side joggers are mobile so as to enable perfectly aligned stacks to be formed. Isolated sheets may be extracted for inspection if required, without stopping production. For this operation the front jogger can be tilted clear and the sheet flow momentarily interrupted by a conveniently located control. The height of the stack is monitored continuously by photocells which cause the stack support table to lower progressively as the stack grows. The upper position of the table is determined by a photocell giving automatic safeguarding against operator error. When the maximum stack is reached an acoustic sounds and the non-stop system begins working. The non-stop system at the delivery comprises an automatically operated blanket which receives the sheets while the stack is being removed allowing production to continue at full speed. A preselecting totalizer counts the sheets as they are delivered and puts the non-stop system into action when the pre-set number of sheets is stacked. Maximum pile height 1300mm. Maximum pile height on Non-Stop curtain 60mm. A tabbing unit is fitted as standard on the machine which inserts indicators at pre-selected intervals.

Monitoring
The progression of the sheets through the machine are monitored by photocells from the platen entry into the delivery. This monitoring system continuously compares the signals from the photocells and stops the machine if a sheet is absent or torn. A touchscreen display is fitted as standard, which shows the machine information and any problems or faults are shown by written instruction.

Controls
The main control switches and push buttons are duplicated at various points around the machine to simplify surveillance and allows the operator to intervene more promptly if necessary. The machine stops automatically at a preselected point in the platen and stripping unit when tooling is to be removed.
