  • Contact welding heating component and automatic welding machine
    Patent number: 10894372
    Abstract: A contact welding heating component and to an automatic welding machine for plasticizing the edges of thermally fusible/meltable material sheets disposed so as to overlap at least partially. A roughening device for the material sheets, which is disposed upstream of the trailing-material edge of the heating component in the direction of movement of the contact welding heating component, protrudes beyond the upper side of the heating component and/or the lower side of the heating component, wherein the roughening device extends transversely to the direction of movement of the contact welding heating component, adjoining the trailing-material edge of the heating component, and includes a number of sharp-edged raised roughening elements extending in the direction of movement of the contact welding heating component, preferably having a variable height in the direction of movement of the contact welding heating component. The automatic welding machine includes a contact welding heat component thus designed.
