59-65 m Loop Foam Cutting Machine with 60-130 m/min Speed and 0.6-170 mm Thickness

The C818A is built for long material. Cutting length is 59-65 m, so a foam line or a long block runs through the machine without a break, and the endless loop blade keeps cutting at 60-130 m/min. Sheet thickness runs 0.6-170 mm with ±0.1 mm precision on 0.6-5 mm sheet, cutting height is 1300 mm, width is 1100-2300 mm, the main drive is 131 kW and the machine weighs 60 T.

Continuous work is a different problem from single-block work. The blade is in the material for minutes at a time, so heat, tension and joint condition all matter more than they do on a short pass. The C818A runs a loop blade with a tension unit and a guided cut, which is what lets it hold thickness over a 59-65 m run instead of drifting in the middle.

1. Check the run length. Confirm the material length is inside the 59-65 m cutting length.
2. Set the thickness. Choose the sheet thickness from 0.6 mm to 170 mm.
3. Set the speed. Pick the cutting speed within 60-130 m/min for the foam grade.
4. Start the pass. The loop blade enters the material and stays in the cut for the whole run.
5. Watch the edge. Monitor the sheet edge and thickness at intervals through the run.
6. Finish and re-load. Take off the last sheet, then set up the next run.

On a long run, the checks that matter are the ones you make while the machine is cutting: sheet edge, thickness at intervals, and blade sound. Catching a drift at five metres costs one sheet; catching it at fifty costs the run.

Over a long pass, thickness drift usually comes from three things: blade tension, blade heat and guide wear. Tension changes as the loop warms, heat changes the joint, and guide wear lets the blade wander slightly. None of them produce an obvious fault, which is why the sheet is measured at intervals rather than only at the start.

The second factor is the material itself. Foam density varies across a long block, and a block that has been stored on a cold floor cuts differently at the bottom than at the top. Setting the speed for the grade, not for the first metre, keeps the thickness consistent through the run.

The third factor is the take-off. On a 59-65 m run the operator has to keep up with the sheet; if the take-off stops, the cut has to stop, and a stopped blade in foam leaves a witness line. Plan the stacking so the pass is not interrupted.

• Tension first: check the loop tension before a long run, not after the first drift.
• Measure at intervals: two or three checks through the run, not only at the start.
• Plan the take-off: a stopped pass leaves a witness line in the sheet.

• Long run capability: 59-65 m of cutting length keeps the blade in the material for the whole batch.
• Stable speed: 60-130 m/min held through the pass, so thickness does not drift with feed.
• No blade marks: the loop blade stays in the cut, so the sheet has no entry or exit witness line.
• Thickness range: 0.6 mm to 170 mm from the same setting, from thin sheet to thick padding.
• ±0.1 mm precision: held on 0.6-5 mm through the length of a long block.
• 131 kW drive on a 60 T frame: the feed rate holds when the block gets dense.
• CE certified: built for export markets with CE guarding and electrics.

• Continuous foam lines: sheet taken off a running foam line.
• Long block conversion: 59-65 m blocks sliced in one pass.
• Mattress production: comfort layers in long repeat runs.
• Packaging foam: protective sheet in long lengths.
• Lamination feed stock: uniform sheet for downstream bonding.
• Stock conversion: long blocks converted to sellable sheet.

Loop blade faults show up early. Check the first sheet of each block at both edges and the middle, and one rejected sheet replaces half a shift of scrap.

Continuous work needs a layout that lets the material feed in and the sheet leave without a fold. Allow clear space on the feed side for the block or line, and on the take-off side enough room for the sheet to stack flat for the length of the run.

The machine is 60 T, so the floor and foundation are part of the installation. Vibration from another machine on the same slab will show in the sheet on a long run more than on a short one.

• Feed side: clear route for long blocks or line output, no sharp edges to snag the foam.
• Take-off side: flat stacking area for the length of the run.
• Blade line: keep hands and tools clear while the loop is running.
• Stop discipline: if the run must stop, mark the point and cut out the witness line.

Long runs put more hours on the blade per shift than single-block work, so check the edge and the joint more often. A loop blade that has run for hours at high speed should be checked for joint wear before the next batch, not after it fails in the cut.

The tension unit and the guide are the two adjustments that hold thickness through a run. Log the tension setting and the guide clearance, and re-check both after any blade change so a repeat run starts from a known condition.

• Every shift: blade edge, joint condition, guide clearance, tension.
• Weekly: guide wear, drive belt and pulley, dust extraction.
• Monthly: lubrication, cabinet check, thickness verification at the start and end of a run.
• After a blade change: re-set tension and guide, then cut a measured test run.

The machine ships in export packing with the head blocked and the frame braced. At 60 T, agree the heavy-lift plan and the container or flat-rack booking before the shipment date, and confirm access at the receiving site.

Delivery is 45 working days after downpayment, payment by T/T or L/C, minimum order one set. Spare loop blades, guide parts and remote commissioning support can ship with the machine.
