 Foam Screening Spline and Window Screens

The newest trend in the market of mechanical stuffs is the foam screening spline which is going to be a subject of necessity for all window screens for years to come. The biggest advantage of this foam screening spline is that it is durable even when exposed to certain elements.

A spline, or the more modern term "flexible curve", is basically nothing but a long strip fixed in position at a number of points that relaxes to form a smooth curve. In earlier centuries, before computers had arrived, drafting tools were used by designers for drawing by hand. The elasticity of the spline material reduced or minimized the require energy for bending it between fixed points and thus, the smoothest possible shape was formed.

Interestingly, foam screening spline devices help bend the wood for musical instruments such as pianos, violins and the violas. In fact, the Wright Brothers used one spline device in order to shape the wings of their aircraft, which was the stepping stone and foundation of aviation in the world.  

Window screens primarily as well as secondarily maintain the view and airflow of windows while protecting against insects from flying or crawling inside the house. So, the spline is highly necessary and extremely beneficial in order to hold the screening securely in windows and doors, allowing continued support of the screen. To bring the screen to perfection and tidy in order, it is trimmed, brushed and sharpened with a sharp utility knife close to the spline. It is commonly known that average spline sizes vary from 3.6mm to 4.8mm, with increments of 0.25 mm sometimes, at an occasional basis. Spline rollers are also very important during the whole process. Some of them are double ended and have both convex and concave rollers.
