However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Moreover, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the particular shapes, configurations and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

Further, spatially relative terms such as "under 8230; \8230;," 'under 8230; \8230;, \8230, under', "\8230, below", "under \8230; \8230, above", "on", "at 8230; \8230, above", "higher", "side" (e.g., as in "side wall"), etc., are used herein to describe the relationship of one element to another (other) element as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "at 8230 \8230; below" may include both an orientation of above and below. Moreover, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the present application, the term "upstream" (or "downstream") means that one component is located upstream (or downstream) of another component with respect to the moving path of the base cloth. For example "the expander roll is located downstream of the radiant heating plate", that means: the spreader roll is located downstream of the radiant heating plate in terms of the moving path.

As shown in fig. 1, the present invention provides a composite device 100 for TPU sheets, which can press a base fabric 10 and a TPU material into a TPU sheet.
