Abstract
A welding device is provided for welding plastic strips or the like to one another which includes a mounting frame carrying an upper welding shoe with rollers engageable with an upper strip of plastic as well as a lower welding shoe with rollers engaged against a lower strip to be welded. The upper and lower shoes are rigidly connected by the frame so that the complete welding device is supported exclusively at the welding strips with no requirement for further backing for the strips being welded other than the lower welding shoe.
