20130118690 | Tubular Heater With External Thermocouple - The problems associated with the prior art have been overcome by the present invention, which describes a tubular heating element having a more reliable and accurate temperature monitoring system. The tubular heating element has a thermocouple attached to its exterior surface, in close proximity to the cutting and sealing portion of the tubular heating element. In addition to improving the accuracy of the temperature measurement, this technique reduces electromagnetic interference caused by the interaction between the heating wire and the thermocouple. | 05-16-2013 |
20130032295 | HINGED TUBULAR HEATER FOR SIDE SEALING MACHINE - A tubular heating element which is resistant to damage caused by foreign material is disclosed. The tubular heating element is pivotably attached to the side sealing machine at its leading (upstream) edge. The trailing (downstream) edge of the tubular heating element is moved by means of a compressible force, such as an air cylinder. In this way, the air in the cylinder pushes the tubular heating element downward into the plane of the film. However, a foreign object located on the film can overcome the force of the air cylinder, thereby lifting the tubular heating element out of the path of the film. | 02-07-2013 |
20130031870 | INTERCHANGEABLE CUTTING ELEMENTS FOR SEALING MACHINE - A sealing machine adapted to support a plurality of different heating/sealing/cutting mechanisms, including tubular heaters and heated cutting blades, is disclosed. The sealing machine utilizes a common interface and mounting system for all side sealers. In addition, in some embodiments, the control system within the sealing machine is adapted to monitor and control the temperature of these various mechanisms automatically so as to create proper seals. | 02-07-2013 |
20110192119 | SIDE SEALING MODULE WITH SEAL COMPRESSION - The present invention describes an improved side-sealing machine for use with heat sealable films. Briefly, a cutting and sealing element is located between a set of cooperating guide and alignment members. The downstream guide and alignment member also includes a compression mechanism. This compression mechanism serves to compress the seal created upstream, and to draw the heat away from the film. In some embodiments, the downstream guide and alignment member also serves to separate the film into a surplus portion and a remaining portion, where only the remaining portion is subjected to compression. | 08-11-2011 |
