Silicone Strip Construction
This roller uses silicone strips for the web-contact spreading surface. It is a distinct product type from a continuous rubber-covered bow roller or an aluminium moving-slat spreader.
PARTS & ACCESSORIES
Silicone Strip Spreader Rollers
DJH manufactures and supplies silicone strip spreader rollers for web-spreading requirements. Review the stationary-shaft arrangement, wrap angle and roller-face length together with the material and installation drawing.
Component reference · dimensions and interfaces determine compatibility
APPLICATION & REQUIREMENTS
Product Construction and Supply Options.
Stationary Core Shaft
The listed shaft arrangement is fixed rather than rotating. Confirm the shaft ends, supports and working-face dimensions against the installation.
Web Path and Spreading Duty
Assess the actual web, wrap angle and required spreading result. The listed spreading values are configuration conditions, not a guaranteed increase in finished-web width.
CONFIGURATION & SELECTION
What to Confirm Before Ordering
Web Characteristics
Identify the material, width, thickness and sensitivity to stretching or surface marks.
Installation Geometry
Provide the web path, wrap angle, mounting location and the space available. Installation conditions influence spreading behaviour.
Desired Result
Describe slack edges, wrinkles or lane-separation requirements. Define a practical acceptance condition for the actual web.
CONFIGURATION & SELECTION
From Drawing to Replacement Part.
Start with an original drawing where available. Mark critical interfaces, contact surfaces and any dimensions measured from a worn part. Confirm the finished drawing, material, quantity and inspection requirements before manufacture or replacement.

SILICONE STRIP CONFIGURATION
Operating and Spreading Conditions.
| Parameter | Listed condition |
|---|---|
| Spreading amount · face length below 1,100 mm | 18 mm |
| Spreading amount · face length above 1,100 mm | 25 mm |
| Line speed | Below 180 m/min |
| Web wrap angle | 90°–180° |
| Core shaft | Fixed, non-rotating |
Confirm the spreading specification at exactly 1,100 mm face length. Roller dimensions, web characteristics and installation conditions must be assessed together; the listed spreading amount is not a guaranteed increase in finished-web width.

Compare the Included Scope
Identify material, finish, dimensions, mounting interfaces and quantity for each component. Agree drawings and any inspection documentation needed for the replacement.
Agree the Order and Delivery Details
Provide quantity and destination. Confirm price, currency, delivery basis, packing, production schedule and any excluded freight or import charges in the quotation.
Define Acceptance and Support
Agree dimensional, surface and material acceptance before ordering. Confirm installation responsibilities, warranty terms and replacement-part identification in the proposal.
BEFORE YOU SPECIFY
Questions Buyers Ask
How does this differ from a rubber bow roller?
The silicone strip spreader, rubber-covered bow roller and aluminium-slat expander use different constructions. Specify the existing arrangement and required spreading result.
Does the core shaft rotate?
The listed silicone strip configuration uses a fixed, non-rotating core shaft. Confirm support and shaft-end dimensions for the installation.
Is the spreading value a guaranteed web-width increase?
No. Review the listed roller conditions against the material, tension and installation. Define the required result and assess it using representative web.
What applies at exactly 1,100 mm face length?
The listed spread conditions distinguish face lengths below and above 1,100 mm. Confirm the spreading specification at exactly 1,100 mm with the proposal.
