Abstract
A welder for joining two polymeric sheets together using a wedged heating element allows for a heating profile on opposite faces of the heating element to be varied by controlling where each of the polymeric sheets contacts the corresponding face.
Claims17
A method of joining a first polymeric sheet and a second polymeric sheet together by thermal bonding, the method comprising:
- providing a welder comprising:
- a heating element having a first face defining a first heating length and a second face defining a second heating length, the first heating length equal to the second heating length;
- and
- a guide plate, wherein a portion of the guide plate covers a portion of the first face to reduce the first heating length to less than the second heating length;
- using the guide plate to convey the first polymeric sheet to the first face of the heating element so that the first polymeric sheet travels less than the first heating length;
- and
- using the guide plate to convey the second polymeric sheet to the second face of the heating element so that the second polymeric sheet travels the second heating length.
