Patent number: 6481071Abstract: The description refers to a facility for needling of fleece with a needle bar (6) taking up at least one needle board (1), which is driven to and fro via axially displaceable pushing rods (7, 8) by means of an eccentric drive (11). To facilitate a longer needle board in fleece feed direction, we suggest to fix the needle bar (1) at two rows of pushing rods (7, 8), arranged in tandem at some distance from each other in fleece feed direction and connected via a crosshead (9), and to make the eccentric drive (11) act upon the crosshead (9).Type: GrantFiled: June 6, 2000Date of Patent: November 19, 2002Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Monika Fehrer, Hannes Pum, Alois Öllinger

Patent number: 6389665Abstract: The description relates to a facility for needling of fleece with at least one needle board driven to and fro in stitching direction, which can be additionally driven in pendulum fashion in fleece feed direction (15) by means of an eccentric drive, which is provided with a connecting rod (3) articulated to a rocker arm (4) and a connecting pitman (8) to the needle board effective on this connecting rod assembly. To be able to easily adjust the rocking amplitude of the needle board in fleece feed direction (15) it is suggested that the swivel bearing (5) of the rocker arm (4) is seated on a rotatable crank arm (6) and that, for adjustment of the rocking amplitude of the connecting pitman (8), the neutral rocking position of the rocker arm (4) is adjustable via the crank arm (6) between an end position essentially running in the direction of the connecting pitman (8) and an end position running transverse thereto.Type: GrantFiled: September 19, 2000Date of Patent: May 21, 2002Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Helmut Fuchs, Robert Strasser, Hannes Pum, Günther Feyerl, Ludwig Legl, Hellmuth Stachel

Patent number: 5758394Abstract: A rotary needling process including a multitude of felting needles repeatedly driven into a fibrous structure disposed on a surface of a needle penetrable support as the support is rotated about an axis of rotation.Type: GrantFiled: August 1, 1997Date of Patent: June 2, 1998Assignee: The B.F. Goodrich CompanyInventors: John S. Linck, Edward Lee Morris, Jr., Hannes Pum

Patent number: 5513423Abstract: The described apparatus for needling a circular nonwoven web, particularly a nonwoven web having the configuration of a circular ring, comprises a needle board, which carries a multiplicity of needles and is adapted to be driven to reciprocate said needles in a predetermined piercing direction. The apparatus also comprises a turntable (1), which comprises a web support that is adapted to support the nonwoven web. The needle board is provided with needles only in at least one sector-shaped region, which has the configuration of a sector with respect to the axis of rotation of the turntable.Type: GrantFiled: April 18, 1995Date of Patent: May 7, 1996Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Heinrich Jakob, Hannes Pum

Patent number: 5320015Abstract: Apparatus for applying a fleece band (1) to an endlessly circulating support web (2) in contiguous coils comprises a fleece band feed device (3) movable transversely relative to the support web (2) and an edging device (10) for the fleece band run supplied to the support web (2). To ensure a uniform fleece band feed in the edge zone of the support web (2), the edging device (10) comprises at least one edging cutter (15) which moves in the vicinity of the fleece band coil adjoining the support web edge at a relative speed in relation to the feed device (3) which corresponds to the relative cross-feed of the feed device (3) compared to the support web (2), but is opposite to this cross-feed.Type: GrantFiled: September 11, 1992Date of Patent: June 14, 1994Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Klaus Minichshofer, Peter Muller, Hannes Pum

Patent number: 5257712Abstract: In an apparatus for applying a non-woven web to a moving carrier web, a straight configuration of the longitudinal edges of the non-woven web being applied to the carrier web is obtained by controlling the feeding speed of the feeder for the non-woven web in dependence on the distance between the carrier web and an unguided course of the non-woven web extending between the carrier web and a preceding fixed guide leading the non-woven web to the carrier web.Type: GrantFiled: September 16, 1992Date of Patent: November 2, 1993Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Klaus Minichshofer, Peter Muller, Hannes Pum

Patent number: 5193424Abstract: In an apparatus for applying a nonwoven web to a carrier web moving in the same direction, it is to be ensured that the nonwoven web has straight longitudinal edges as it is applied to the carrier web. This is accomplished in permitting the unwound nonwoven web to sag freely in a slack loop between the unwinding station and a feeding conveyor which precedes the edge-trimming device. The velocities of conveyance of the feeding conveyor and of the take-off rolls have a predetermined ratio in dependence on the velocity of the receiving surface on which the carrier web receives the nonwoven web and are controlled in such a manner that the nonwoven web will be subjected to a predetermined tensile stress between the take-off rolls and the carrier web.Type: GrantFiled: June 18, 1991Date of Patent: March 16, 1993Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Klaus Minichshofer, Hannes Pum

Patent number: 4977653Abstract: In order to increase the latitude regarding the distribution of needles in a needle board in a direction which is transverse to the direction of travel of a web which is to be needled in an apparatus for needling the web while it is supported by a deck provided with a grate of parallel blades, it is proposed to arrange the blades of the grate so that they extend transversely to the direction of travel of the web.Type: GrantFiled: January 30, 1990Date of Patent: December 18, 1990Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventor: Hannes Pum

Patent number: 4962576Abstract: In a process in which a non-woven strip is needled to a revolving endless carrier web, adjacent convolutions of the non-woven strip should exactly adjoin each other. For that purpose each convolution of the non-woven strip is initially needled to the carrier web with the exception of a marginal portion, which constitutes a free longitudinal edge, and that marginal portion is needled after the position and direction of the free longitudinal edge have been detected.Type: GrantFiled: November 16, 1989Date of Patent: October 16, 1990Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Klaus Minichshofer, Peter Muller, Hannes Pum

Patent number: 4701986Abstract: In apparatus for applying a sliver at a bias to an endless backing web in the making of a paper machine felt, a needle machine is preceded by a sliver feeder, which is operable by a traversing drive to perform a traversing movement across the working width of the needle machine. Irregularities can be avoided because an automatically controlled position-correcting mechanism is provided, which serves to compensate any deviation of the actual course of one longitudinal edge of the backing web from a predetermined, desired course of said longitudinal edge, and means are provided for controlling the traversing drive so that the traversing movement of the sliver feeder will be influenced by changes of the width and/or length of the backing web.Type: GrantFiled: June 19, 1986Date of Patent: October 27, 1987Assignee: Textilmaschinenfabrik Dr. Ernst Fehrer AktiengesellschaftInventors: Feyerl Gunther, Augustin Kalteis, Hannes Pum
