摘要： A method of venting a rear facer sheet for lamination is accomplished by continuously drawing the rear facer sheet through a perforating device which creates conical apertures in the rear facer. Two metal rails affixed to opposing edges of a front facer are continuously drawn into a laminator after first having an expanding foam material continuously deposited onto the upper surface of the front facer. The perforated rear facer is continuously drawn into the laminator and affixed to the two metal rails, creating an enclosed volume in which the expanding foam is located. The apertures in the rear facer allow for the escape of gasses and air during lamination, promoting even flow and uniform density of the foam material. The perforating device has an upper and a lower rotating cylinder, the lower cylinder being equipped with piercing elements and the upper cylinder being equipped with grooves corresponding to the piercing elements.
摘要翻译：用于层压的后表面板的排气方法是通过连续地将后表面片材穿过穿孔装置来完成的，所述穿孔装置在后表面中产生锥形孔。首先将膨胀的泡沫材料连续地沉积到前表面的上表面上之后，将固定到前表面的相对边缘的两个金属导轨连续地拉入层压机。穿孔的后表面连续地被拉入层压机并固定在两个金属导轨上，从而产生膨胀泡沫所在的封闭容积。后表面中的孔允许在层压期间排出气体和空气，促进泡沫材料的均匀流动和均匀的密度。穿孔装置具有上下旋转筒，下筒装有穿刺元件，上筒装有与刺穿元件对应的槽。

摘要： A method of forming a door panel is accomplished by providing a plurality of spaced rollers. A first plastic facer is drawn beneath the rollers wherein the first facer is in the form of a continuous sheet having an upwardly facing surface. A second plastic facer is drawn beneath the rollers, and is in the form of a continuous sheet and at least a portion of the second facer is spaced above the first spacer. A pair of rails are positioned on opposed sides of the first facer and drawn beneath the rollers. A foam material is deposited on the upwardly facing surface prior to drawing the first facer beneath the rollers. The foam material expands and hardens to adhere together the first facer, second facer and rails into a continuous length of assembled panel.
摘要翻译：一种形成门板的方法是通过提供多个隔开的辊来实现的。第一塑料面被牵引在辊之下，其中第一面是具有向上表面的连续片的形式。第二塑料面被拉伸在辊之下，并且是连续片的形式，并且第二面的至少一部分在第一间隔件上方间隔开。一对轨道定位在第一平面的相对侧并且被拉到辊之下。在将第一表面拉到辊之下之前，将泡沫材料沉积在面向上的表面上。泡沫材料膨胀并硬化以将第一面，第二面和轨道粘合到连续长度的组装面板中。
