摘要： A frame includes a plurality of screen bar segments. To form the screen bar, a flat malleable strip is provided. The strip is roll-formed to form a tube having a tensioning step on its face. The tensioning step extends along a length of the tube. The tensioning step has a mounting surface, which may be the bottom of the tensioning step. A hot-melt adhesive is applied to the mounting surface. The screen is spread across the frame, so that the screen extends over the mounting surface of each screen bar segment. The screen is secured to the face of the frame with an adhesive at a plurality of positions across a length of the mounting surface of at least one screen bar segment. The adhesive may be a hot melt adhesive. The screen is inserted with a plurality of pins to intermittently suspend the screen in the adhesive across the length of the screen bar segment. An apparatus for securing the screen to the screen bar segment includes a support surface that holds a screen bar segment. A heat source applies heat directly to the adhesive to melt the adhesive on the screen bar segment. The apparatus is capable of actuating the pins to cause the screen to contact the adhesive. The pins may embed the screen deeply enough to contact the mounting surface beneath the pins, while the screen is intermittently suspended in the adhesive between pins.

摘要翻译： 框架包括多个屏幕条段。 为了形成屏幕条，提供了一个扁平的可延展的条。 带材被卷成形成在其表面上具有张紧台阶的管。 张紧步骤沿管的长度延伸。 张紧步骤具有安装表面，其可以是张紧步骤的底部。 将热熔粘合剂施加到安装表面。 屏幕分布在框架上，使得屏幕在每个屏幕杆段的安装表面上延伸。 屏幕通过粘合剂在至少一个屏幕杆段的安装表面的长度上的多个位置处固定到框架的表面。 粘合剂可以是热熔粘合剂。 屏幕插入有多个销，以间隔地将屏幕悬挂在屏幕杆段的长度上的粘合剂中。 用于将屏幕固定到屏幕杆段的装置包括保持屏幕杆段的支撑表面。 热源将热量直接施加到粘合剂上以熔化屏杆上的粘合剂。 该装置能够致动销以使屏幕接触粘合剂。 针脚可以将屏幕嵌入深度足以接触销下方的安装表面，同时屏幕间歇地悬挂在销之间的粘合剂中。

摘要： An apparatus secures ventilation cloth to a screen frame. A screen frame is oriented in an approximately vertical position. The screen frame has a plurality of segments. Each segment has a mounting surface on a face thereof. At least one of said segments has adhesive on the mounting surface thereof. A ventilation cloth is hung across the mounting surface of said one segment. The adhesive in said one of the segments is melted. The ventilation cloth is inserted in the adhesive across a length of said one of the segments.
