1250 mm Cutting Height Vertical Foam Cutter with 6900 mm Band Knife and 1.68 kW Motor

• 1250 mm cutting height: a full foam block is split in one pass, which removes the pre-splitting step and the extra handling that comes with it.
• 6900 mm band knife loop: the longer loop runs cooler than a short blade, so the slice stays straight and the blade holds its edge through a full shift of dense block.
• 1320 x 2500 mm inner table: the block is squared on the fixed table before it reaches the blade, so the first slice and the last slice of a block are the same thickness.
• 1.68 kW drive with guarded belt: the motor holds speed through a dense rebonded block, which is where a light drive stalls and marks the slice.
• Hardened, adjustable guide wheels: blade tracking is set with a handwheel and checked in a minute, which is the first thing to verify when a slice drifts.
• Welded box column: the wide foot and the stress relieved column keep the blade line rigid when a block is pushed through at production feed rate.

• 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.
