Abstract
The invention is directed to a process to manufacture an interconnected stack of thermoplastic frames having two sides by stacking the thermoplastic frames to obtain a stack of frames such that the facing sides of two neighbouring frames are in contact with each other at a contact area. When stacking a longitudinal conduit is formed which runs along the length of the stack and a branched conduit is formed at the contact area. The interconnected stack of thermoplastic frames are obtained by supplying a pressurised melt of a plastic material to the elongated conduit and branched conduits.
Claims18
A process to manufacture an interconnected stack of thermoplastic frames having two sides by
- stacking the thermoplastic frames to obtain a stack of frames such that the facing sides of two neighbouring frames are in contact with each other at a contact area,
- wherein as a result of stacking the frames and as a result of at least one opening present in the frame at least one longitudinal conduit is formed which runs along the length of the stack,
- wherein as a result of stacking the frames and as a result of an elongated gutter as present on or in at least one side of the frame at the contact area a branched conduit is formed at the contact area, which branched conduit is fluidly connected to the longitudinal conduit, and
- wherein a pressurised melt of a plastic material is supplied to the elongated conduit and branched conduits while the stack is held together by external means to obtain the interconnected stack of thermoplastic frames.
An interconnected stack of thermoplastic frames having two sides wherein the facing sides of two neighbouring frames are connected by fusion bonding at a contact area.
