In professional window covering production, pleating machines and pleat setting machines serve different stages of the workflow. This page clarifies the distinction, the impact on drapery quality, and how to select the right approach for your line. Pinch pleat remains the most commonly used pleat in draperies, and adjustable Microflex hooks help fine-tune installation results. As a leading manufacturer of innovative, high-quality automation equipment for the window covering industry, Eisenkolb focuses on machines that form consistent, production-ready pleats with superior efficiency and global support.
Definitions and core function
A pleating machine forms the pleat structure in the header of the drapery with precise, repeatable spacing, depth and height. In production, the fabric is measured, folded and secured—often with buckram tape for pleat headings—so the pleat geometry is locked in before finishing and packaging. Eisenkolb pleating machines also automate the insertion of adjustable Microflex hooks, ensuring consistent hook alignment at speed and reducing manual handling.
A pleat setting machine is finishing equipment that stabilises or reinforces existing folds using steam, heat and pressure. It does not create the structural header pleat or determine spacing. Instead, it helps the fabric retain its shape and drape after sewing or pleating, particularly with synthetic blends that respond well to heat. In natural fibres, pleat setting improves presentation but is less permanent than in synthetics. Eisenkolb’s portfolio is centred on automated pleating machines; a dedicated pleat setting machine is not listed. For equipment options that support this step, see pleat setting (pressing) solutions.
Selection checklist: use cases and decision points
Choose a pleating machine when your priorities include:
- Structural pinch pleats with exact spacing, depth and height for made-to-measure or series runs
- High first-time-right results, minimal rework and reliable hook position
- Programmable variation within jobs for made-to-measure draperies
- Integration with Microflex hooks to allow on-site drop and level adjustments
Consider a pleat setting step when your priorities include:
- Enhancing crease memory in polyester and blends along the full drape length
- Improving presentation after transport or storage by reconditioning folds with steam and pressure
- Supporting consistent fan-folded presentation after confection using a Prefolder that fan-folds finished draperies
For an overview of relevant equipment, see curtain finishing machines.
In practice, many lines combine both: a pleating machine defines the geometry in the header, followed by pressing or steaming—using a finishing table such as the DEKO-2000—to stabilise folds and prepare the order for packing or installation.
Quality, consistency and productivity
Because a pleating machine controls spacing, depth and height during the pleat-forming step, it directly determines header accuracy, seam appearance and visual rhythm across panels. Automated hook insertion ensures uniform pick-up points, improving stack-back symmetry and level hang. A pleat setting process can enhance crease retention and polish the final appearance but cannot correct spacing errors introduced earlier. For productivity, pleating automation reduces operator fatigue and variability, shortens changeovers for made-to-measure orders and keeps throughput stable over shifts. Finishing with steam or heat is then a fast, low-risk post-process that preserves the result achieved upstream.
Materials and pleat types in drapery production
Material response drives how much pleat setting helps after pleating. Polyester and polyester-rich blends typically respond strongly to steam and heat, retaining folds well over time. Cotton and linen can be shaped and presented cleanly, but their crease memory is more sensitive to handling, humidity and laundering. The structural integrity of the header is therefore best secured by accurate machine pleating regardless of fabric type.
In terms of construction, pinch pleat is the most commonly used pleat in draperies. Other options include knife pleats and box or inverted box pleats for tailored looks. Tucks are stitched folds used decoratively or for shaping, but unlike structural pleats in the header they rarely define the hanging geometry of the drapery. Accurate machine control of spacing and depth keeps these styles consistent panel to panel, while pleat setting improves presentation and long-length crease definition. For gathered headers, dedicated machines for pencil pleating help standardise spacing and fullness. For current design perspectives, see The most modern curtain pleat in 2026.
Eisenkolb solutions for automated pleating
Eisenkolb manufactures pleating automation for both made-to-measure and series production, with consistent quality and comprehensive global support and training. Representative systems include:
- EPS-2200: a semi-automatic solution for single pleats with automatic Microflex hook insertion.
- MPS-2600: an automatic machine for single and double pleats with Microflex hook insertion for higher daily volumes and repeatable quality.
- PPS-2300: a fully automatic machine for double and triple pleats with Microflex hook insertion. It offers programmable options for made-to-measure draperies with variations in pleat spacing, depth and height, plus a seam-hiding function.
Microflex adjustable hooks allow fine adjustment of drop and level at installation without altering the header, helping to achieve a true, level finish across tracks or poles. Combined with precise machine pleating, this reduces on-site corrections and supports a reliably premium appearance.
Pleating machine vs pleat setting machine: side-by-side
The following comparison summarises where each approach adds value in a modern drapery workflow.
| Aspect | Pleating machine | Pleat setting machine |
|---|---|---|
| Primary role | Forms structural header pleats with defined spacing, depth and height | Stabilises existing folds using steam, heat and pressure |
| Stage in process | Core construction step before final finishing and packing | Finishing step after pleating and sewing |
| Quality impact | Determines geometry, seam visibility and hook alignment | Enhances crease memory and presentation along drape length |
| Materials | All common drapery fabrics including polyester, cotton and linen | Strongest effect on synthetics and blends |
| Adjustability | Programmable spacing, depth and height on appropriate models | Process parameters for steam, heat and dwell time |
| Typical automation | EPS-2200, MPS-2600, PPS-2300 with automatic Microflex hook insertion | Steam tables or pressing equipment in finishing |
| Output readiness | Production-ready headers with consistent hook positions | Improved drape presentation prior to packing or installation |
FAQ
What is a pleating machine?
A pleating machine automates the formation of pleats in the drapery header with precise spacing, depth and height. It reduces variability, speeds production and can automate hook insertion. The result is a consistent, production-ready header that hangs level and repeats accurately across panels.
What is a pleat setting machine?
A pleat setting machine is finishing equipment that uses steam, heat and pressure to stabilise folds after sewing or pleating. It improves crease memory and presentation, especially in polyester blends, but it does not create or correct header spacing and depth.
What are the two types of pleats?
In drapery production, pinch pleat is the most commonly used pleat. Foundational pleat families include knife pleats and box or inverted box pleats. These define the look and stack of the drapery, and benefit from accurate machine control of spacing and depth.
What is the Perfect Pleater device?
Perfect Pleater is a manual aid used to prearrange fabric into evenly spaced folds for temporary or preparatory work. It is useful for small-scale tasks but does not replace industrial pleating machines that form and secure structural header pleats at production speed.
What is the difference between tucks and pleats?
A tuck is a stitched fold for shaping or decoration, often narrow and used in vertical rows. A pleat is a formed fold that defines the architecture of the drapery header and its hang. Pleats set spacing, depth and stack behaviour, while tucks are primarily decorative.
