  • Patent number: 5745966
    Abstract: A singeing device (V) for the gassing of circular goods (1), for instance circular knitted textile goods, having a singe burner (3) and a cloth guide (W) in order to obtain uniform gassing. The guidance of the goods (W) is developed so as to result in flat sides (a) of the circular goods (1) which extend substantially parallel to each other and rounded transition sides (b), and the singe burner (3) gasses the circular goods (1) both on the flat sides (a) and on the transition sides (b).

  • Patent number: 5727937
    Abstract: A burner unit for the singeing of flat textile structures and the like, in particular a burner unit for singeing machines having a combustion chamber and ramp stones forming one or more singe slits, the combustion chamber being fed from a gaseous mixture chamber via preferably two or more parallel burner slits. A ramp stone is arranged adjustably movable for changing the singe slit and/or the combustion chamber.

  • Patent number: 4641403
    Abstract: A machine for flame processing textile fabric webs (27), especially a singeing machine, is equipped with a burner unit (35) which comprises a combustion chamber terminating in a singeing slit, connected to a gas mixing chamber by a mixture feed slot (7).To save energy, the width of the working flame should be adjustable continuously and with low operating cost, whereby in particular provision should be made for automatically adjusting the flame width to the width of the fabric web (27) being processed. For this purpose, the burner unit (35) is provided with one or two flexible sealing strips (13) for the mixture feed slot, said strips being insertable from one or both ends of the burner unit, each of said strips further having its outer end wound on a winding body (33), rotatable for adjusting the inner ends of sealing strips (13).

  • Patent number: 4627135
    Abstract: A burner unit for a flame treatment of flat textile materials includes a combustion chamber terminating in a singeing slot supplied from a gas mixture chamber by two parallel burner slots, with the gas mixture chamber being encased by a burner element including two substantially U-shaped profile members clamped together along longitudinal edges with an interposition of mixture distributing rail for delimiting the burner slots respectively along a longitudinal side. To achieve a significant uniformity of the singeing flame in a longitudinal direction, the mixture distributing rail is enclosed between two guide strips respectively defining the outer longitudinal side of the burner slots, with the guide strips being clamped together with the mixture distributing rail, as a package, between the two substantially U-shaped profile members.
