Patent ID: 7318255

Claim:
A cross lapper for manufacturing a fiber fleece from a fiber web, comprising: a supply arm having lower and upper ends and pivotably mounted at its lower end around a stationary lower pivot axis; a downwardly extending laying arm having upper and lower ends and pivotably supported at its upper end on the supply-arm upper end around an upper pivot axis parallel to the lower pivot axis, the laying-arm lower end movable in a substantially straight path; an endless output conveyor extending substantially parallel to the pivot axes and having a laying zone below the path of the laying-arm lower end; two reversing rollers supported on a common carriage that is disposed below the output conveyor and is movable transversely thereto; two endless transport belts juxtaposed for substantially continuously clamping and transporting the fiber web to be layered and guided along the supply and laying arms for receiving a fiber web at an infeed zone and for laying a fiber web in the laying zone on the output conveyor under pivoting movement of the supply and laying arms, the juxtaposed belts forming a discharge nip at the laying-arm lower end, the belts extending beyond the nip in opposite directions transversely across the laying zone in proximity to the output conveyor, the belts being separately guided to the respective reversing rollers, back to the laying-arm lower end, and from there along the laying and supply arms to the infeed zone; and drive apparatus for moving the belts, pivoting the supply and laying arms, and moving the output conveyor.
