Pin Plates
Pin Plate For Stenter Machines
The standard pin plate: two rows of roughly 5 mm pins at 3 to 4 pins per cm on a hardened base plate.
Product Overview
A pin plate is the part that actually holds the cloth on a pin stenter. The common pin stenter carries pins about 5 mm long, mounted in two rows at roughly three to four pins per centimetre along the base plate. The pins are thicker near the base so the fabric never rests directly on the hot base plate.
The plate sits on a pin plate holder, and the holder is attached to the chain. A press wheel pushes the fabric down onto the pins so it stays there and travels forward with the chain. Because pinning grips the cloth harder than a clip can, it lets you raise fabric tension and run faster: up to 100 m/min.
Key Benefits
- Increases fabric tension so the cloth runs faster, up to 100 m per minute
- Two-row pin layout at 3 to 4 pins per cm grips across the full selvedge, not at one point
- Pins thickened at the base keep the fabric off the hot base plate
- Interchangeable with the pin plate holder you already run once the profile is matched
Who It Is For
- Finishing mills whose stenter speed is limited by how well the cloth is held
- Maintenance engineers replacing a worn pin bed section by section
- Buyers sourcing a repeatable pin plate specification across several frames
Problems It Solves
- Cloth pulling off the pins at speed and creating width faults
- Scorch marks where fabric has been resting against a hot base plate
- Mixed pin plate specifications across one machine giving inconsistent selvedge appearance
Application Scenarios
- General woven and knitted finishing where line speed is the constraint
- Replacing a pin bed where pins have bent, broken or lost their point
- Frames being converted from clip to pin operation for higher throughput
Technical Features
- Pins approximately 5 mm long
- Two rows of pins, approximately 3 to 4 pins per centimetre
- Pins thicker near the base to prevent direct fabric contact with the hot base plate
- Silver and yellow finish, supplied to match the existing bed

Quality Control
- Pin height measured across the plate, not only at the ends
- Pin straightness and point condition checked on every plate
- Base plate flatness verified so the plate seats fully on the holder

Certifications. We make no certification claim for this part. The original company statement is that products comply with international quality standards; no certificate is named and none is asserted here. Ask us directly if your procurement process requires documentation.
Comparison With Other Options
Pin plates versus clips: clips leave no pin marks in the selvedge and suit thicker fabrics, but pins allow higher tension and faster running, and customers generally accept the pinholes that come with pin stenters. Within pin plates, the differences are pin length, density and base profile, all of which follow the machine and the article.
Use Guide
Match the new plate against the removed one for pin height and base profile before fitting
Fit plates in sequence and check that adjacent plates sit at the same height
Set the press wheel so it pushes the cloth fully onto the pins without bearing on the plate
Inspect for bent pins at every maintenance stop and replace the plate rather than straightening pins
Renew a full section at once so pin height stays consistent along the chain

FAQ
Questions About Pin Plate For Stenter Machines
How long are the pins?
About 5 mm, mounted in two rows at roughly three to four pins per centimetre. That is the common pin stenter arrangement and it is what we supply unless you specify otherwise.
How fast can I run with pin plates?
Pinning increases the tension you can hold on the fabric, so the cloth runs faster. On our customers' lines this reaches 100 m/min.
Will pinning mark the selvedge?
Pin stenters leave pinholes in the selvedge. Clip stenters do not, but they cannot hold the same tension. In practice customers accept pinholes in the selvedge on pin stentered goods.
Can you match my existing plate?
Yes. Send a plate or a dimensioned photo and we match pin length, density and base profile.
What is the minimum order?
Pin plates are normally ordered by the metre of chain or by section. Tell us the frame width and how much of the bed you are renewing and we quote accordingly.
How are they packed for export?
Boxed in layers with the pin faces protected, then palletised. Pins are the part that damages in transit, so the packing is built around protecting them.

Guides That Cover This Part
What Is a Stenter Machine and How Does It Work
The stenter heat-sets and dries fabric by stretching it to width and holding it there under controlled heat.
Key Parts of a Stenter Machine
Entry section, clip or pin chains, rails, heating chambers, exhaust, blowers, temperature control, width adjustment and weft straightener.
Pin Stenter or Clip Stenter Which To Use
Clips leave no pin marks and suit thicker fabrics; pins hold more tension and run faster, to 100 m per minute.
Send A Sample And We Will Match The Profile
Seat profiles and geometry changed across frame generations, so the part itself is more reliable than a model number. We identify it and quote the matching specification.
