1-100mm Slice Vertical Slitter Foam Cutting Machine with 6900mm Band Knife

• Five materials on one table: PU sponge, EVA, PE, EPE pearl cotton and cardboard are cut on the same blade and the same table, so a mixed order does not need a second machine.
• 1 to 100 mm slice thickness: the thickness guide covers thin packaging sheet and thick furniture slab on the same setting block, checked with a rule at the discharge side.
• 1320 x 2500 mm inner table: a stacked EVA or PE sheet set is squared before the blade, so the slice thickness stays even across the full width.
• 6900 mm band knife: the long loop runs cool through a stacked sheet set, which keeps the edge clean on EPE pearl cotton that marks easily.
• 1.68 kW drive: speed holds when the material changes from soft sponge to a dense EVA stack, so the operator does not reset the feed mid order.
• Compact column with wide foot: the frame stays rigid on a stacked sheet set, which is where a light vertical cutter starts to chatter.

• Band knife loop: 6900 mm on the standard frame and 7600 mm on the oversize frame, so the blade runs cool and holds a straight line through a 1250 mm block.
• Table: a fixed inner table plus a sliding external table, both in flat steel, which lets a full block be squared before it reaches the blade.
• Guide wheels: hardened and adjustable, they set the blade tracking and are the first part to check when a slice drifts in thickness.
• Frame: welded box section with a wide foot, which keeps the column rigid when a dense rebonded block is pushed through.
• Drive: 1.68 kW motor with a guarded belt drive, and an emergency halt switch on the operator side of the column.

• Mattress plants: splitting full foam blocks into slab stock and trimming the block square before the contour line.
• Furniture foam converters: cutting seat and backrest blanks from 1250 mm block, then bevelling on a second pass.
• Packaging producers: slicing EPE and EVA into sheets and inserts for electronics and instrument packing.
• Footwear material suppliers: splitting EVA and PE sheet stock to thickness before pressing and die cutting.
• Recycling and rebonding lines: trimming rebonded blocks to size before lamination and cutting.
• Insulation and construction foam: squaring PE and EVA board stock to a fixed thickness for panel assembly.

1. Set the slice thickness on the external table guide and lock it, then check the setting with a steel rule before the first block.
2. Start the band knife and let it reach full speed, since a blade started into foam will stall and mark the slice.
3. Load the block on the inner table, push it against the guide and square the face against the column reference.
4. Feed the block through the blade with the pusher, keeping the feed rate even so the blade does not bow in a dense block.
5. Return the table, take the slice off on the discharge side, and stack it flat so it does not take a set.
6. Check every tenth slice with a rule and adjust the guide if the thickness drifts more than 1 mm.

• Take the standard frame when your blocks stay within 1320 * 2500 mm, which covers the bulk of mattress slab work.
• Take the oversize frame when you run 1650 mm wide block or when the block is loaded by forklift and needs the wider approach.
• Order the 7600 mm blade as a spare on the oversize frame, because the longer loop is the part that decides the changeover interval.
• Add a thickness guide with a digital readout when you cut to a fixed thickness for packaging, where a 1 mm drift is a rejected batch.

Set the frame on a level floor and anchor the four feet, then check the column for plumb with a spirit level. A column that leans will produce a slice that is thinner at one edge, and no guide adjustment will correct it. Allow 1500 mm of clear space at the discharge side for the sliced stock and for the operator.

Fit the band knife, set the tension to the value on the label, and track the blade on the guide wheels with the handwheel while the machine runs at low speed. Run a scrap block at three thicknesses, measure each slice at four points, and record the result on the commissioning sheet before the machine goes into production.

• The band knife is guarded on the column side and behind the table; the guard is opened only for a blade change with the isolator locked out.
• The emergency halt switch sits at the operator position and is tested at the start of every shift.
• Push the block with the pusher handles and keep hands behind the table edge while the blade is running.
• Never leave the machine running unattended, and never reach across the blade line to take a slice off the table.
• Wear cut resistant gloves and eye protection, and keep the floor clear of foam offcuts that can trip the operator.

Every frame is checked for square after welding and again after assembly, and each machine runs a scrap block at 20 mm, 50 mm and 100 mm slice settings before packing. The slice is measured at four points and the reading is written on the test sheet, alongside the motor current at duty load. The serial number is stamped on the column plate so that a guide wheel or a blade order can be matched to the build, and a CE declaration travels with each set.

The frame ships nude packed with plastic film and foam sheet, the band knife is boxed separately, and the guide wheels, pusher handles and small parts travel in a wooden case. A 4000 * 4000 * 2500 mm frame needs a 40 ft container. Delivery is about 30 working days after the down payment; we send loading photos and the packing list before the container leaves Qingdao.
