The decking board further comprises at least two oval holes (1 1 ) between the first side (3) and the second side (2). Also, there is a first distance (8) between one of the at least two oval holes (1 1 ) and the second side (2), a second distance (9) between the oval holes (1 1 ) and a third distance (18) between one of the at least two oval holes (1 1 ) and the first side (3). This invention further relates to a method and a system for manufacturing the decking board.
Abstract:
The invention relates to a process and apparatus for the homogenization of feed stock. According to the invention, solid stock material is mixed in at least two successive homogenization steps (1), wherein each homogenization step comprises at least two adjacent tanks (2), and the stock material is fed into adjacent tanks of a first homogenization step (IA), at least two stock flows are conducted out form each tank of each homogenization step, and at least one stock flow is conducted from each homogenization step into at least one tank (2) of the following homogenization step.
Abstract:
The invention relates to a method and a device for producing chaff used in the production of a wood composite material. In accordance with the invention, adhesive laminate waste comprising adhesive material, glue and release material is arranged into chaff in multiple steps and the adhesive properties of the glue are killed.
Abstract:
The invention relates to a multi-layered heat-sealable material for structures closed by sealing and capable of being opened from the sealing point (7) by pulling free, such as for heat-sealed product packages (1). In addition, the invention relates to packages comprised of the material in question. In particular are considered lids (5) of cups and package boxes (4) which can be pulled free as well as package bags formed by sealing the material against itself. The material is comprised of a base layer (8) of paper or cardboard, a polymeric support layer (9) functioning for example as an air lock, and an outer polymer-based heat-sealing layer (10), in which according to the invention is mixed polystyrene, acrylate copolymer, and a fine inorganic substance such as for example talcum. A material according to the invention is sealable in a peelable manner to for example polyethylene, polyester or polystyrene.
