Triangular Rolling Space for Mineral Wool Density Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rolling mineral wool bands or mats result in highly fluctuating roll density, causing issues in manufacturing consistent insulating pipe sections.
Innovation Solution
The use of three belt conveyors forming a triangular rolling space, where one conveyor conveys the mineral wool and the others are hinged to adjust rolling pressure based on roll size, maintaining constant density across the roll.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rolling methods are used with fixed rolling elements, then the rolling process is simple, but the roll density becomes highly fluctuating and inconsistent
Solution Approach 1:
The rolling elements are designed as belt conveyors with hinge assemblies that enable dynamic repositioning during the rolling process. As the roll grows in size, the belt conveyors automatically adjust their positions to maintain optimal rolling pressure, transforming the static rolling system into a dynamic one that adapts to changing roll dimensions, thereby ensuring consistent density throughout the roll.
Solution Approach 2:
The system changes the physical parameters of the rolling elements by using belt conveyors instead of rigid rollers. The belt conveyors can change their effective rolling radius and position as they wrap around the growing roll, allowing the rolling pressure parameters to be dynamically adjusted to maintain constant density despite increasing roll size.
2Manufacturing precision
If rigid rollers are used as rolling elements, then the device structure is simple, but soiling occurs and density control is poor
Solution Approach 1:
The patent replaces traditional rigid mechanical rollers with belt conveyors as the rolling elements. This substitution introduces a flexible, continuous surface that reduces soiling of the mineral wool material while enabling better density control through the hinge assembly mechanism that adjusts belt position and rolling pressure during the rolling process.
3Manufacturing precision
If rolling pressure is applied uniformly, then the process is simple to control, but density varies across the roll as it grows
Solution Approach 1:
The hinge assembly mechanism provides automatic feedback adjustment: as the roll increases in size, the hinge assemblies detect the change in roll diameter and automatically reposition the belt conveyors to maintain the correct rolling pressure. This closed-loop adjustment ensures that density remains constant across the entire roll without requiring manual intervention or complex control systems.

Function Achieved in This Case

AI summary
The invention relates to a method and device for making a roll (12) from a mineral wool band or mat (11), wherein the mineral wool band or mat is rolled in a rolling space (R) defined by three rolling elements (1, 2, 3) between themselves. In the method and device, the cross-section of said rolling space (R) in a direction perpendicular to the rolling axis of a rolling motion is substantially in the shape of a triangle, and the density of the mineral wool roll (12) is adjusted according to a change in the size of the rolling space (R) brought about by a change in the size of the roll in such a way that the density of mineral wool remains substantially constant across the entire roll (12).
