AI Technical Summary
Technical Problem
Existing joining devices are inadequate for bonding sheets of materials with different physical and chemical properties, particularly in the manufacturing of heat-not-burn articles, as they do not effectively join materials like tobacco-containing sheets and paper or plastic.
Method used
A joining device with a punch plate and counter plate, featuring arrays of joining protrusions and holes, that perforate and mechanically deform sheets to create a strong bond, suitable for various materials including paper, plastic, and metal.
Benefits of technology
The device achieves a strong and reliable bond across diverse materials by interpenetrating sheets through protrusions and holes, enabling continuous manufacturing processes without interrupting production lines.

Abstract
The joining device (2) comprises a punch plate (240) and a counter plate, which are movable relative to each other to join two material sheets (4, 3) that can be positioned between the punch plate (240) and the counter plates (250, 241). The punch plate (240) comprises an array of joining protrusions (70), and the opposing counter plates (250, 241) comprise an array of joining holes (80). The array of joining holes comprises a number of joining holes, and the array of joining protrusions comprises a number of joining protrusions, with the number of joining holes being at least the same as the number of joining protrusions. The positions of the joining protrusions in the array of joining protrusions correspond to the positions of the joining holes in the array of joining holes.
