1300 mm Cutting Height Loop Foam Cutting Machine with 0.6-170 mm Thickness

The C818A is an endless loop blade machine for blocks that are tall and wide. Cutting height is 1300 mm, cutting width is 1100-2300 mm, and sheet thickness runs from 0.6 mm to 170 mm with ±0.1 mm precision on 0.6-5 mm sheet. Cutting speed is 60-130 m/min on a 131 kW drive, machine weight is 60 T and the machine is CE certified.

Tall blocks are where a loop machine earns its place. A 1300 mm block cut with a reciprocating blade needs the blade to enter and leave the material; an endless loop blade stays in the cut, so the block is sliced from the top face down without a re-clamp. The frame has to be stiff enough and heavy enough that the cut stays straight over 2300 mm of width, which is what the 60 T structure is for.

1. Check the block. Confirm the block height is inside the 1300 mm cutting height and the faces are square.
2. Load and align. Bring the block onto the table and align it to the blade line.
3. Set the thickness. Choose the sheet thickness from 0.6 mm to 170 mm.
4. Set the speed. Pick a cutting speed within 60-130 m/min for the foam density.
5. Run the pass. The loop blade stays in the cut and the sheet comes off the top face.
6. Take off and stack. Remove each sheet flat, then continue to the end of the block.

Because the blade does not leave the cut, the sheet face has no entry or exit mark and the block does not need re-clamping between sheets. That is the practical difference on a 1300 mm block.

Cutting height and machine weight are related. A blade travelling through 1300 mm of foam at 130 m/min carries a load into the frame, and if the frame flexes the sheet gets thicker on one side of the block than the other. A 60 T structure is what keeps the cut line straight at full width and full height.

Cutting width sets the handling. At 2300 mm the sheet needs a take-off table and a stacking route as wide as the machine, otherwise the operator folds the sheet and the fold line is scrap. On wide sheet the material is soft enough that a crease stays visible after the sheet relaxes.

Density matters too. The machine works well from 15 to 50 kg/m3. Above that the blade sees more resistance, the feed rate has to come down and the blade wears faster, so the cut speed should be set from the foam grade rather than from the maximum figure on the plate.

• 1300 mm blocks: load at table height with a lift; a dropped block loses its square face.
• 2300 mm width: plan a take-off route as wide as the block.
• Density 15-50 kg/m3: reduce speed for the high end of the range.

• Tall block capability: 1300 mm of cutting height takes full mattress blocks without a pre-cut.
• Wide cut: 1100-2300 mm of width, held straight by a 60 T frame.
• Endless loop blade: the blade stays in the cut, so there is no blade entry and exit mark on the sheet face.
• Thickness range: 0.6 mm to 170 mm covers comfort layers, backing sheet and thick padding.
• ±0.1 mm precision: held on 0.6-5 mm sheet, which is the range buyers measure.
• 60-130 m/min: speed is set per foam grade, from soft sponge to higher density PU.
• 131 kW drive: feed rate holds through dense blocks rather than slowing in the cut.

• Mattress blocks: comfort layers and support sheet from 1300 mm high blocks.
• Furniture foam: seat, back and armrest padding in repeat thicknesses.
• Wide sheet conversion: 2300 mm wide sheet for lamination and quilt backing.
• Packaging foam: protective sheet and inserts from wide blocks.
• Acoustic foam: sheet cut to a fixed thickness across the full width.
• Foam stockists: blocks converted to sellable sheet thicknesses.

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.

A 60 T machine needs a level, anchored foundation and clear space on both sides. The loading side needs room for a lift or a roller table; the take-off side needs 2300 mm of clear width plus pallets at table height.

Operators should be trained on the two things that decide sheet quality: block alignment and blade condition. A block that is not square to the blade line produces a wavy first sheet no matter what thickness is set.

• Foundation: level slab, machine anchored, no other vibrating equipment on the same pad.
• Loading: lift or roller table for 1300 mm blocks; keep hands clear of the blade line.
• Take-off: pallets at table height, 2300 mm clear route.
• Housekeeping: clear foam dust at every block change; dust in the guide opens the tolerance.

The loop blade and its guide carry the tolerance. Check the blade edge and the joint at the start of each shift, keep the guide clear of dust, and follow the sharpening interval for the foam grade. A loop blade that is starting to dull still cuts 100 mm sheet cleanly while leaving a taper on 1 mm sheet.

The tension unit deserves a daily look. A loop that runs slack wanders in the cut, and a loop that runs tight loads the joint. Both show up as thickness variation before they show up as a break.

• Every shift: blade edge, blade joint, guide clearance, dust at the head.
• Weekly: blade tension, guide wear, drive and feed condition.
• Monthly: lubrication, cabinet dust, thickness check against a gauge.
• After a blade change: re-set the guide and cut one measured test block.

The machine ships in export packing with the head blocked and the frame braced. At 60 T it needs a heavy-lift plan and a confirmed container or flat-rack booking before shipment, and the receiving site door width should be checked against the machine width.

Delivery is 45 working days after downpayment, payment by T/T or L/C, minimum order one set. Installation guidance, remote commissioning support and spare loop blades are available with the machine.
