Abstract
Apparatus for making corner joints of sealing plastic profiles, or moldings, for windows, doors or the like, including a base plate on which two profile holding means, each having a bottom formed with a groove for accommodating the continuous profile to be held and a pivotable lid for covering or opening the accommodating groove are mounted, one fixedly and one pivotally. A welding means pivotable relative to the holding means, is provided which cuts the miter with the holding means in line and heats the cut edges. The pivotal holding means is moved toward the fixed one and the cut and heated edges of the profile are welded together.
Claims18
Apparatus for making corner joints from lengths of profiles of plastic material comprising:
- a base,
- a pair of profile holding means on said base, one of said profile holding means being pivotally mounted relative to said base, said pair of profile holding means when aligned holding a continuous length of the profile which extends into both said holding means, each of said profile means having an oppositely angled side across which the profile extends such that when the two profile holding means are aligned a section is formed which has an included angle between said sides which opens towards the front faces of said pair of profile holding means, and
- heat welding means including a blade which fits within the angled sides between the two profile holding means to cut the profile extending into said section and to heat the edges of the pieces of profile remaining in each of said holding means,
- the pivoting of said one profile holding means bringing the heated edges of said profile pieces into contact to weld said pieces and hold the same together.
