The invention relates to a belt roller system for applying a surface structure in a floor panel or wall panel, said system comprising at least one upper endless belt and at least one lower endless belt, wherein each belt is rotatable around at least two pulleys, and at least one drive unit for rotating the upper endless belt and/or the lower endless belt. At least part of the upper endless belt comprises a surface structure and/or at least part of the lower endless belt comprises a surface structure. The upper endless belt and the lower endless belt are positioned substantially parallel to each other such that a panel can be transported between the upper endless belt and the lower endless belt such that the surface structure of the upper endless belt and/or the surface structure of the lower endless belt is transferred into the panel upon transport of the panel between said upper endless belt and said lower endless belt.

A 3D thermoplastic pultrusion system and method based upon a 3D variable die system and including one or more sets of 3D thermoplastic forming machines to continuously produce thermoplastic composite pultrusions with at least one of varying cross-section geometry and constant surface contours, varying cross-section geometry and varying surface contours, and constant cross-section geometry and varying surface contours. The 3D thermoplastic pultrusion system and method including at least one of one or more pairs of shapeable and flexible dual-temperature bands and a rotating assembly that rotates the one or more sets of 3D thermoplastic forming machines to impart a twist to the thermoplastic composite.

An apparatus (10) for producing reshaped plastic granules from a plurality of initial granules (12) with a predetermined shape is disclosed comprising: a feeding unit (20) for continuously receiving a plurality of said initial granules (12), a pressing unit (30) for mechanically reshaping the initial granules, said pressing unit comprising at least two opposite pressing surfaces (32) with a gap (34) therebetween, the width (W) of said gap ranging from 0 mm to 0.5 mm, a receiving chamber (40) for receiving the reshaped final granules (13) from the pressing unit, and a frame (50) for supporting the feeding unit, the pressing unit and the receiving chamber. A method is also provided to produce final granules by mechanically reshaping the initial granule, each final granule having a certain surface-to-volume ratio and a primary thickness of at most 0.7 mm within substantially the entire volume of the final granules.

A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.

A calender for the treatment of web-like materials, including a fixed structure adapted to support two heated rollers shaped to be connected to the fixed structure, to a drive unit and to a heating system. The calender includes automatic elements for engaging and respectively for disengaging the rollers to and from the fixed structure, the drive unit and the heating system; the automatic elements are controlled by a programmable control unit and each of the rollers has an engaging surface shaped to be engaged by mechanical elements for moving the rollers which move the rollers between the calender and one or more waiting or parking stations while the rollers are at a temperature between 50° C. and 200° C.

The present application provides a calender, a floor production line and a production method using the calender, wherein the calender comprises a calendering roller rack and a set of calendering rollers arranged on the calendering roller rack. The set of calendering rollers comprises a plurality of calendering rollers arranged in a line and not vertically. The present application changes the arrangement of the calendering rollers. The calendering rollers are arranged in a line, not vertically. This arrangement reduces the overall height of the calender, decreases the requirements of the calender on the height of the factory building and facilitates long-distance transportation by containers. Using the calender to assemble the floor production line, the height space of the factory building occupied by the production line can be saved.

Calender for the treatment of web-like materials, including a fixed structure supporting two heated rollers reciprocally arranged so as to form a nip traversable by web-like materials, where each roller has pins mounted on bearings. The structure includes two lower levers and two upper levers adapted for exerting on the bearings forces oriented according to not coinciding directions, each lever being connected with an actuator that controls its rotation around a horizontal axis to put it in a first engagement position of the respective bearing and in a second release position, such that in the second position of the levers the extraction of the rollers from the calender is allowed.
