Patent number: 9701507Abstract: The coiled foil rolls are reinforced in their edge region by folding. The coiled foil rolls are made by supplying a foil to coiling devices; cutting the foil in a conveying direction with a knife so that at least two foil sections are created which extend in a conveying direction; folding the edge regions of the foil sections by a folding device and laying the folded sections and the remaining part of the foil section on each other; and coiling the foil sections with the coiling devices. The knife or the folding device are moved simultaneous oscillating back and forth in a direction transversal to the conveying direction during the coiling of the foil sections.Type: GrantFiled: April 29, 2015Date of Patent: July 11, 2017Assignee: SML MASCHINENGESELLSCHAFT M.

Patent number: 7896283Abstract: An arrangement for winding up at least two material webs, in particular film webs, having at least two receiving devices, for the rotatable mounting of at least one winding core each. The receiving devices are transferable between a winding position for winding up at least one material web on the winding core, and a removal or loading position, respectively, for removing at least one winding core which has finished being wound up, or for feeding at least one empty winding core. At least two winding cores are coaxially arranged in the receiving device for simultaneously winding up the material webs on separate winding cores, the winding cores each being rotatably mounted in two bearing sites adjacent to the respective winding core. The receiving device has at least three carrying arms, one winding core each being mounted between two carrying arms.Type: GrantFiled: May 30, 2006Date of Patent: March 1, 2011Assignee: SML Maschinengesellschaft M.B.H.Inventors: Adolf Tauber, Robert Preuner

Patent number: 6129882Abstract: The invention relates to an apparatus for manufacturing multifilament threads with at least one hot-air module 6 for drawing or relaxing the thread Y. To manufacture multifilaments with particularly high strength and to avoid the problems of the bearings of the rollers 9, 10 in the hot-air modules 6, at least one apparatus is provided for screening the hot stream of air from the rollers 9, 10, 10' of the or each hot-air module 6. Such apparatus may, for example, take the form of divider sheets 12. To facilitate the introduction of the thread Y into the hot-air module 6, it may be furthermore provided according to the invention that two rows of rollers 9, 10 facing each other are arranged in the or each hot-air module 6, at least the rollers 10 of one row being arranged in the direction of the rollers 9 of the other row and movable beyond these so that a meander-shaped arrangement of the thread Y can be achieved automatically in the hot-air modules 6.Type: GrantFiled: March 11, 1999Date of Patent: October 10, 2000Assignee: SML Maschinengesellschaft m.b.H.Inventor: Bruno Haider
