Industrial upholstery foam cutting machine

01

Match the block size and cutting tool

Bäumer's OFS-222 is a horizontal contour cutting machine with an oscillating knife, listed with a standard working size of 2,300 mm width, 1,300 mm height and 2,300 mm length, and options of 2,600, 1,500 and 2,600 mm. Bäumer lists it for high volume weight foams and technical precision parts, names its materials as ether- and ester-based polyurethane, flame-protected and high resilience PU foam, viscoelastic foam, combustion-modified highly resilient PU foam, melamine formaldehyde resin and reticulated PU ester foam, and notes that oscillating knives need no back-turning on a contour. [1] Its OFS-Twincut carries a circulating and an oscillating knife in one cutting unit, at the same standard dimensions, and adds natural rubber to the material list. [2] sitola's SCC-E contour cutter works with a revolving bandknife and states a cutting height of 1,300 mm, cutting length of 2,300 mm and working width of 2,300 mm, each extendable as an option, for the furniture, mattress and packaging industries. [3] Its SCC-W works with a revolving endless cutting wire over 1,300 mm height, 2,200 mm length and 2,200 mm width, and is aimed at PU foam, EPS and mineral wool in the insulation industry. [4]

For trimming and dividing blocks, sitola's SVC-A vertical cutter has a stationary table and a moving cutting unit, a standard working width of 1,250 mm each side of the bandknife (options 1,600 or 2,200 mm), a cutting length of 2,200 mm (options 2,600 or 3,100 mm) and a cutting height of 1,300 mm (options 1,000 or 1,500 mm). It uses a smooth or toothed band blade for flexible PU foam, or a band saw with set teeth for rock wool and foams of very high density. [5]

Editorial calculation: assuming a rectangular block fills the listed OFS-222 working dimensions with no clearance or holding allowance, 2.3 × 2.3 × 1.3 m gives approximately 6.9 m³. Assuming the listed optional width, length and height can all be supplied together, 2.6 × 2.6 × 1.5 m gives approximately 10.1 m³. These are geometric scenarios, not manufacturer-declared usable block capacities or measured processed volumes. Confirm the combined option and the actual clearances. [1]

Give the supplier the largest block (length × width × height), the foam grades and densities to be cut, sample cushion drawings or DXF files, whether 3D parts need a 90° turntable, the cutting tool wanted (oscillating knife, bandknife or wire), the CAD or nesting software in use, the power supply, and the floor space and foundation available.

02

Compare cutting speed, hold-down, dust and safety

Cutting speed depends on the tool. Bäumer lists the OFS-222 at max. 10 m/min, and the OFS-Twincut at max. 60 m/min with the circulating knife and max. 10 m/min with the oscillating knife. [1] [2] sitola states up to 60 m/min for the SCC-E (depending on material and contour), up to 10 m/min cutting (depending on material and contour) and up to 25 m/min positioning for the SCC-W, and up to 45 m/min at the cutting unit and 8 m/min at the side stops for the SVC-A. [3] [4] [5] To hold the foam, the SCC-E uses an automatic hold-down device and a motor-driven center holder, the SCC-W a vacuum unit that stops light materials slipping, and the OFS-222 a sheet holding-down device and a center support that reduces the free knife length and absorbs the cutting pressure. [3] [4] [1]

sitola’s SCC-W description provides cutting-dust extraction and wire cooling. Bäumer describes cutting with micro-toothed or ground knives as dust-free; that statement does not cover every tool/material or the optional grinding process. The SVC-A description lists a 3 kW blade drive braked when its safety circuits trigger, and optional sanding-dust extraction. [4] [1] [5] The SCC-E page states supplied guarding and CE certification, and separately requires the purchaser/operator to check the safety equipment against current national requirements. Obtain the actual delivered configuration and documents; the catalogue statement is not an independent compliance audit. [3]

Editorial calculation: assuming one straight 2,300 mm pass at a constant maximum speed throughout, with no acceleration/deceleration, cornering, reversal, knife change or handling time, 2.3 m ÷ 10 m/min × 60 s/min = 13.8 s, and 2.3 m ÷ 60 m/min × 60 s/min = 2.3 s. The source assigns those maxima to different OFS-Twincut tools. These are ideal travel-time scenarios, not manufacturer-published cycle times, measured cutting runs or a throughput comparison on the same foam/contour. [2]

03

Trial the cushion contour on the specified foam and tool

Use the actual foam grade, density, block arrangement and part contour for an acceptance cut. Record the delivered holding device, cutter, control/software, extraction and guarding, then agree the dimensional and edge checks. The listed machine speeds distinguish tools and configurations; acceptance needs the actual part. [2] [3]

Pair the moving cutter with its table, holding and extraction

05

Record block axes and tool-dependent acceptance limits
