Patent number: 7526838Abstract: In a camel-back fleece laying machine with a laying arm attached to a joint, two endless card web transport belts are guided along this arm, and the bottom end of the laying arm carries a discharge gap, which is moved by an upper carriage transversely to the transport direction of an output conveyor belt in a plane above the output conveyor belt. A laying carriage is guided at a certain height between the output conveyor belt and the upper carriage on a path extending parallel to the upper carriage, and two closely adjacent deflecting rolls are mounted in the upper carriage, over each of which a cover belt is guided. The cover belts form a laying gap at the deflecting rolls, through which gap a card web supplied by the card web transport belts is conducted. The drive of the laying carriage is independent of the drive of the upper carriage, and the path of movement of the upper carriage extends beyond the path of movement of the laying carriage at least at one end.Type: GrantFiled: April 19, 2007Date of Patent: May 5, 2009Assignee: Oskar Dilo Maschinenfabrik KGInventors: Johann P.

Patent number: 5473802Abstract: A brush structure for use as a stitch support for a velour needle loom comprises bristle tufts inserted into a carrier plate, with their free ends forming a continuous support surface for supporting thereon a fiber batt to be needled. The foot portions of the bristle tufts are of polygonal cross-section, resulting in a high packing density of the bristle tufts on the carrier plate and optimum bristle-coverage thereof. This enables excellent continuity of the support surface formed by the free bristle ends to be achieved without the bristles having to be provided with a curl or crimp.Type: GrantFiled: November 29, 1993Date of Patent: December 12, 1995Assignee: Oskar Dilo Maschinenfabrik KGInventor: Johann P.

Patent number: 5371928Abstract: Apparatus for feeding a fiber batt to a needle loom, in which a gusset gap between an upper reversing roller of a pre-compression means and an upper supply roller is filled by an upper slim transmission roller rotatably suspended at its end portions by bracket means. The transmission roller is made from a carbon fiber reinforced resin material. The bracket means are composed each of two parts which may be released from each other. One part of each bracket means is mounted on the axis of the supply roller, whereas the other part is suspended in a stationary frame of the apparatus. By realeasing the parts of each other, an easy disassembly of the supply roller is enabled.Type: GrantFiled: August 24, 1993Date of Patent: December 13, 1994Assignee: Oskar Dilo Maschinenfabrik KGInventor: Johann P.

Patent number: 5307546Abstract: Apparatus for feeding a fiber batt to a needle loom, in which a gusset gap is filled between the reversing roller of an upper pre-compression conveyor band and an upper supply roller by means of a slim transmission roller, which is suspended at its length at several locations, in order to avoid sagging. The suspensions can consist of ribbons, which carry the transmission roller, or they can be formed by holding fingers which are integrally formed with guide fingers of a finger roller and which are located in respective circumferential grooves in the transmission roller. In an alternative the transmission roller is divided into several segments and roller bearings are provided at the connection positions of the segments and are suspended from above (FIG. 1).Type: GrantFiled: August 4, 1992Date of Patent: May 3, 1994Assignee: Oskar Dilo Maschinenfabrik KGInventor: Johann P.
