摘要： An improved roofing tile with side flanges, one overlying and one underlying, providing an interlock between adjacent tiles. The flanges have two ridges and two grooves each. The inner ridge of the underlying flange is higher than the outer ridge thereof, and the outer groove of the overlying flange is deeper than the inner groove thereof. Optionally a cutout is provided on the overlying flange permitting a tile to be held with a hurricane clip on the underlying flange. Optionally a cavity is provided on the bottom face toward the lower edge to prevent a tile coming in contact with nails driven through tiles in a lower course.

摘要： An arrangement for the thermoforming of molded plastic articles from a continuous web of a thermoplastic material, and more particularly, a trim in place thermoforming arrangement in which the plastic articles are simultaneously molded and at least substantially or completely separated from the remaining thermoplastic web material. A high degree of alignment and precision is obtained between cooperating cutting blades employed in the trimming of the thermoformed articles, because of a unique self-aligning or floating support structure of at least one of the cutting blades operating in conjunction with the thermoforming apparatus. The self-aligning action provided for between the slidingly contacting cutting blades allows for an automatic compensation for any temperature changes and blade wear encountered during operation, and with only one movable part being required for the trim in place device.
摘要翻译：一种用于从热塑性材料的连续腹板热成型模制塑料制品的装置，更具体地说，其中塑料制品同时模塑并且至少基本上或完全地与剩余的热塑性网状材料分离的装饰部件。由于至少一个切割刀片与热成型装置一起操作的独特的自对准或浮动支撑结构，因此在热成形制品的修整中使用的协作切割刀片之间获得高度的对准和精度。在滑动接触的切割刀片之间提供的自对准动作允许对在操作期间遇到的任何温度变化和刀片磨损进行自动补偿，并且仅需要一个可移动部件用于修剪就位装置。

摘要： A multilayer structure designed to overcome the shortcomings of previously known thermoformed sheet structures. Articles may be formed by a method of the present invention having an attractive outer appearance associated with polyolefin films containing inert inorganic fillers while having the advantageous processing properties of oriented films. The present invention is directed to multilayer structures, methods for forming the multilayer structures as well as shaped articles formed from the multilayer structures. The multilayer structure has at least a first sheet layer comprising a polyolefin and preferably an inert organic filler, and a film layer which advantageously comprises an oriented polyolefin or polyester. The present invention may comprise one or more of each of the above described sheet and film layers.
摘要翻译：设计用于克服先前已知的热成型片结构的缺点的多层结构。制品可以通过本发明的方法形成，其具有与含有惰性无机填料的聚烯烃膜相关的有吸引力的外观，同时具有取向膜的有利加工性能。本发明涉及多层结构，用于形成多层结构的方法以及由多层结构形成的成型制品。多层结构具有至少包含聚烯烃，优选惰性有机填料的第一片层，以及有利地包含定向聚烯烃或聚酯的膜层。本发明可以包括上述片和膜层中的每一个中的一个或多个。
