A buffer forming method comprises following steps of: providing a honeycomb core, and providing a roller unit to clamp the honeycomb core for continuous pressing and conveying in a stretching direction, and to make the honeycomb core become a buffer through a feed stage, a shaping stage, and a rebound stage. The roller unit defines a feed region, a distance of which is greater than 70% of a height of a sheet material and the distance of which is smaller than the height of the sheet material, in order to make an average bending deformation degree of a plurality of intermediate segments of the honeycomb core substantially smaller than 10% in a pressing and conveying process.

A method for producing a breakable weak point in molded bodies made of fiber-containing material is described. Further, a tool for producing a breakable weak point in molded bodies made of fiber-containing material is described. A molded body made of fiber-containing material is also described. The molded body has at least one surface portion that has at least one region with a breakable weak point.

A simple multi-piece manually operated kitchen tool intended for use in a home or small kitchen wherein this tool is used to form baking liner material into a formed baking liner having flat bottom and fluted sidewalls. The perimeter of the kitchen tool may be designed to form a traditional circular liner as for cupcakes or alternately a rectangle or some other geometric or non-geometric shape such as semi-circle, rectangle, ellipse, star, crescent, sun, heart, etc.

A method for manufacturing three-dimensional products with at least one inclined product portion made of a fiber-containing material using at least one forming tool and a forming tool are described. Vibrations are introduced via a device and this results in an improved compression of fiber-containing material in the region of inclined portions.
