A gusset preheating assembly and a method of using the same. The assembly includes a heating gun assembly mounted on a frame. Spreader rods open up a gap in a bag's gusset and nozzles blow warmed air into the gap. Orthogonally arranged first and second hydraulic members are operatively engaged with heating gun assembly and are activated to move the heating gun assembly vertically or horizontally. Hot air blowing into the gap from the nozzle relaxes the gusset. Pressure is applied to the relaxed gusset, thereby reducing the thickness of the gusset region of the bag. The reduction in thickness makes it possible to increase the number of gusseted bags that are packaged in a container or on a roll.
A moveable seam welding machine, system, and method of use is provided. The seam welding machine includes at least one sensor that generates at least one data point having geolocation coordinates incorporated or integrally formed therewith. The data point typically relates to the integrity or quality of the welded seam created by the machine. The sensor generates data points which may be evaluated in alarm logic for abnormalities or anomalies. The geolocation coordinates inherent or integral to the data point may be plotted or registered overtop satellite imagery. The coordinates of the anomalies or the registered image, or both, can be provided to the workman or operator so he/she may manually inspect the geolocation at where the abnormal or anomaly data point was generated by the sensor to spot check the welded seam by hand.
A machine for welding an overlapped region of two adjacent strips of material and a method of using the same. The machine includes a housing with front and rear ends, a wheel train engaged with the housing for moving the housing across the material; a nozzle on the housing having a welding head at a free end; the nozzle being positionable at least partially beneath the housing's bottom wall for welding the overlapped region; front and rear pressure rollers engaged with the housing, where the front roller is positioned forwardly of the welding head and the rear roller is positioned rearwardly of the welding head; wherein the rear pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a forward direction; and the front pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a reverse direction.

A system and method for welding edge seams at the edges of fabric is presented. A method begins by lowering a fabric pre-fold bar onto a piece of fabric. A pre-aligned portion of the fabric is pushed on top of the pre-fold bar so that the pre-fold bar is between the portion of fabric on top of the fabric pre-fold bar and other fabric below the pre-fold bar. The fabric on top of the fabric pre-fold bar is folded edge fabric and fabric not on top of the fabric pre-fold bar is not folded edge fabric. A folded edge is formed between these two sections of fabric. The method pinches some of the fabric at the folded end and then pulls the folded edge fabric off of the fabric pre-fold bar. After that, the method welds at least some of the folded edge fabric to the not folded edge fabric.
The invention relates to providing a hot wedge welding machine which may eliminate the thermal dampening that occurs to a welding element when the material to be welded is first introduced into the welding machine. The invention relates to cooling the welding element to stimulate a heating system to heat the welding element to the desired temperature. The artificial cooling stress provided by a cooling system is removed generally at the same time genuine cooling stress of the material is applied to the welding element. This results in the welding element maintaining a consistent temperature when the material is introduced into the welding machine.

Bi-directional seaming machine and method of seaming
A seaming machine and method are provided for seaming segments of sheet material to one another to form larger sheets. The machine typically includes a frame with a pair of spaced seaming devices mounted thereon for respectively seaming opposed edges of the segments of sheet material to one another. The process allows for the seaming of multiple sheet segments while the sheet segments remain atop a work surface. Relative back and forth movement between various components and the work surface typically facilitate the process.
