Moving Aluminium Slats
The described construction uses curved hollow aluminium slats, a roller body, inclined wheels and a core shaft. It should be specified as an aluminium-slat spreader rather than a generic smooth guide roller.
PARTS & ACCESSORIES
DJH supplies aluminium moving-slat expander rollers for web-spreading applications. Compare this construction with silicone strip spreaders and rubber bow rollers before specifying a replacement.

Component reference · dimensions and interfaces determine compatibility
APPLICATION & REQUIREMENTS
The described construction uses curved hollow aluminium slats, a roller body, inclined wheels and a core shaft. It should be specified as an aluminium-slat spreader rather than a generic smooth guide roller.
Three groups of curved aluminium slats are arranged around the body, with the middle group fixed to the roller. Confirm the complete moving-slat arrangement on the proposed drawing.
Identify the web, wrinkle pattern and contact geometry. Silicone strip, rubber bow and aluminium-slat constructions are different options and are not interchangeable solely by face dimensions.
CONFIGURATION & SELECTION
Identify wrinkles, slack areas or separation issues and where they occur in the process. Include a photo or layout where possible.
Provide substrate, thickness, width, stretch and surface requirements. Spreading conditions should be assessed for the material.
Specify diameter, face length, mounting and contact path. Confirm the roller construction rather than treating all spreader designs as equivalent.
CONFIGURATION & SELECTION
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.

QUOTATION & SUPPLY SCOPE
Identify the moving aluminium-slat construction, face length, core shaft and mounting. Include the material, contact path and required spreading result when requesting a replacement.
Identify material, finish, dimensions, mounting interfaces and quantity for each component. Agree drawings and any inspection documentation needed for the replacement.
Provide quantity and destination. Confirm price, currency, delivery basis, packing, production schedule and any excluded freight or import charges in the quotation.
Agree dimensional, surface and material acceptance before ordering. Confirm installation responsibilities, warranty terms and replacement-part identification in the proposal.
BEFORE YOU SPECIFY
No. Confirm the proposed construction and how it suits the web and installation.
State the lane-separation requirement and web path. The actual arrangement needs review before suitability is confirmed.
A spreading component is not a substitute for assessing the complete web path and tension system.
