Overlap Seals – Splines, Keders, Zippers
Each month we are featuring an aspect of our heat sealing machines that is an integral component of a good heat sealer. As the only US manufacturer and leading technology producer of heat sealers for the shade and window covering industry, we continue to improve the art of designing and building a first class heat sealing machine so that the quality of our seals are the absolute best seals available.
About a year ago we perfected the most accurate Automatic PocketMaker. Our MicroPrecision folder technology is now standard on all of our ShadeSealers. Our pride in achieving this accuracy resulted in many videos featuring our Automatic PocketMaker.
Several months after introducing this new feature we received inquiries suggesting that our ShadeSealer is limited to making pockets. That’s simply not true. While automatically producing accurate pockets is an achievement, the ShadeSealer is most certainly your best choice for producing overlap seals as well. And, based on our poster-type press technology, the entire process of producing an overlap seal is done from the front of the machine, unlike our Asian competitors that have you walk around the machine several times.
Overlap sealing requires a method to assure alignment. Originally we offered, as an option, use of laser to align overlaps. Unfortunately, laser lines, although high tech looking, are blocked by various heights and placement of shade materials. For best results we use our Riser Sealing Bar technology.
A primary use for Riser Sealing Bar in conjunction with our MultiHead sealing feature , is to seal splines, zippers and keders effortlessly without making any changes to the machine. Additionally, this same Riser Bar provides a hard edge to align the lower or first layer of material when making an overlap seal. To assure that the upper layer of material is perfectly parallel and aligned with the lower layer for either 1/4-inch or 1/2-inch user selectable overlap seal width, the operator locates and places Riser Alignment Guides along the edge. Use of magnets or weights hold position while the overlapped materials are sealed. Detailed instructions are found online at our NovaCare web support pages.
Making overlap seals with the ShadeSealer is very easy to do, and most important, the seals are perfectly aligned, and with our wide format options, you can make a single seal up to 252 inches in less than 10 seconds. And all seals are made with Novaseal’s Pulse Sealing technology which produces the fastest and best quality seals available on more materials than any other competitive method of sealing.
