Disclosed is a floor decoration tile manufacturing system for automatic storage and supply and automatic air duct type control of temperature, the floor decoration tile manufacturing system including: a raw material supply unit configured to store a raw material for forming a lower sheet and a middle sheet; a lower sheet supply unit configured to form and supply the lower sheet; a middle sheet supply unit configured to supply the middle sheet bonded onto the lower sheet; a main roller configured to bond the lower sheet and the middle sheet, which have been supplied; a first sheet supply unit configured to supply a print sheet having a color or a pattern to the main roller; a second sheet supply unit configured to supply a transparent sheet, which is bonded onto the print sheet, to the main roller; and a control unit configured to control a tile manufacturing process through pressing the main roller by controlling the driving speeds of the raw material supply unit, the lower sheet supply unit, and the middle sheet supply unit and rotation of the main roller such that the print sheet and the transparent sheet which have been supplied to the upper side, to which the lower sheet and the middle sheet are bonded, are sequentially pressed, wherein the control unit controls the heating temperatures for the raw material, the lower sheet, the middle sheet, and the tile manufacturing sections.

An assembly to connect together first and second sheet members. The assembly includes a pressure device that applies pressure to the sheet members while the sheet members are in an overlapping arrangement and positioned on a support platform. A sensing system that includes one or more thin film pressure sensors detects the positions of the leading and trailing edges. A connection device connects the members together in an overlapping arrangement.

A supply device (3) for supplying substrate strips (10, 10; 11, 11) to a double-belt press (2) for pressing the substrate strips (10, 10; 11, 11) together includes unwinding stations (4, 5) each having an unwinding shaft (6, 7) for receiving a substrate strip roll (8, 9) and serving to unwind the substrate strips (10, 10; 11, 11) from the substrate strip roll (8, 9), at least one of the unwinding stations (4) having a force-measuring device with a measuring shaft (16, 17) around which one of the substrate strips (10, 10; 11, 11) can be wrapped, an auxiliary shaft (18, 19) being assigned to the measuring shaft, wherein the auxiliary shaft (18, 19) and the measuring shaft (16, 17) of the unwinding station (4) are moveable relative to each other between a guiding position for guiding the substrate strip (10, 10; 11, 11) from the roll of the substrate strip rolls (8, 9) through a gap between the measuring shaft (16, 17) and the auxiliary shaft (18, 19) and an operating position defining a pre-defined and/or pre-definable wrap angle () of the substrate strip (10, 10; 11, 11) around the measuring shaft (16, 17) by an adjusting drive.
