Detailed Overview & Working Principle of Blade & Knife Pleating

The D.I. Blade Type Pleating Machine — widely recognized across the filtration industry as a Knife Type Pleating Machine — is engineered for high-precision, flexible, and uniform pleating of diverse filter media used in automotive, industrial, HVAC, HEPA, and specialty filtration applications.

Unlike conventional rotary pleating machines that require expensive, fixed-diameter roller tooling changes for each pleat dimension, this precision blade/knife pleating mechanism utilizes synchronized reciprocating upper and lower blades. This enables operators to adjust pleat depth and pitch quickly on-the-fly, drastically reducing changeover time, minimizing material scrap, and maximizing manufacturing flexibility for both custom batches and high-volume production runs.

Equipped with dual integrated pre-heating and post-heating temperature-controlled platforms, the machine permanently thermo-sets pleat creases in synthetic media, heavy-duty cellulose paper, wire mesh, and multi-layer composite packs without compromising structural media integrity. The machine is manufactured with a heavy-duty fabricated industrial steel frame, hardened tool-steel folding blades, and precision guide mechanisms for continuous 24/7 vibration-free operation.

Manufactured at our New Delhi headquarters, Dashmesh International supplies, installs, and commissions Blade/Knife Type Pleating Machines across all key industrial manufacturing corridors in India — including Delhi, Haryana, Uttar Pradesh, Himachal Pradesh, Gujarat, Mumbai, Pune, Aurangabad, Telangana, Hyderabad, Bangalore, and Chennai — as well as international export markets worldwide.

Frequently Asked Questions: Blade & Knife Type Pleating Machines

Is a blade type pleating machine the same as a knife type pleating machine?
Yes. Blade type pleating machine and knife type pleating machine are two industrial terms describing the exact same equipment. Both refer to pleating machinery that utilizes synchronized reciprocating upper and lower blades (knives) to fold filter media at precise intervals, unlike rotary pleaters that utilize rotating cylindrical rollers.
What are the standard working widths and pleat depth ranges for this machine?
Our Blade/Knife Pleating Machines are manufactured in working widths of 600 mm, 1000 mm, 1200 mm, 1600 mm, and 2000 mm. Pleat height/depth is continuously adjustable from 5 mm up to 100 mm (and up to 150 mm on extended models) through mechanical or touchscreen PLC controls without replacing pleating rollers.
Why choose a blade/knife pleater over a rotary pleater?
A blade/knife pleater is ideal when you need versatility in pleat dimensions without purchasing expensive replacement rollers for every change in pleat depth. It also excels at folding multi-layer composite media, wire mesh, and delicate HEPA glass fiber that cannot be handled easily on high-speed rotary rollers.
Can this knife pleating machine handle wire mesh and synthetic media?
Yes. The reciprocating blade mechanism is specifically engineered to handle multi-layer packs, including cellulose filter paper, non-woven synthetics, and stainless steel or galvanized wire mesh without tearing or pinching the media.
Do you supply and install blade pleating machines in Delhi, Mumbai, Gujarat, and other states?
Yes. Dashmesh International manufactures and directly supplies Blade/Knife Type Pleating Machines across India, with dedicated installation, commissioning, and on-site operator training provided in Delhi, Haryana, Uttar Pradesh, Himachal Pradesh, Gujarat (Ahmedabad, Rajkot, Vadodara), Maharashtra (Mumbai, Pune, Aurangabad), Telangana (Hyderabad), Karnataka (Bangalore), and Tamil Nadu (Chennai).
What after-sales service and spare parts support is provided in locations like Pune, Hyderabad, or Bangalore?
Our service engineers provide on-site commissioning, machine alignment, and operator training upon delivery. We maintain a large inventory of replacement folding blades, heating elements, sensors, and mechanical spares at our New Delhi facility, ensuring 24-to-48-hour dispatch to Pune, Hyderabad, Bangalore, Chennai, and other industrial centers.
Is PLC automation and recipe storage available?
Yes. The machine can be equipped with a full PLC control system and color touchscreen HMI, allowing operators to store pleating parameters, pleat heights, speeds, and batch counts for instant recall during product changeovers.
