Abstract
There is disclosed an apparatus for folding over and pressing into position the edge strips of two material webs, stitched together along the seam, with two collaborating feeding and pressing devices, in which one of said feeding and pressing devices is in the form of a roller and is assembled from two cylindrical jacket members of identical size, which make contact with their inside facing and surfaces with reference to said roller in a common plane and which are radially displaceable relative to each other.
Claims9
An apparatus for folding over and pressing into position the edge strips of two material webs, stitched together along the seam, comprising two co-operating superposed feeding and pressing devices, one of said feeding and pressing devices including two cylindrical jacket members of substantially identical size, which members are radially displaceably mounted relative to each other and, at their respective outer end faces are axially retained by two respective lateral end plates, in which radial grooves are machined in each lateral end plate at its outer circumference, into which grooves axial cams secured to a respective one of the associated jacket members project, whereby a spacing is maintained between the grooves and the cams, which spacing determines the radial displaceability of the jacket member.
