1. A fleece laying apparatus comprising:
a camel back cross lapper having (a) an infeed zone, (b) an output conveyor, (c) a supply arm, (d) a laying arm with a lower
end reciprocatingly guided on a path above the output conveyor and transverse to an output direction of the output conveyor,
and (e) two delivery transport belts guided in juxtaposed fashion from the infeed zone to the laying-arm lower end; and
variable-volume web buffering apparatus upstream of the infeed zone and adapted to hold a web between two take-up transport
belts at least one of which is one of the two delivery transport belts, the web buffering apparatus including:
a movable common frame; and
frame rollers rotatably mounted on the common frame, the frame rollers including a two-belt roller deflecting the take-up
transport belts by about 180°, and at least two one-belt rollers, the common frame movable transverse the roller axes, at
least one of the one-belt rollers wrapped by the one delivery transport belt, such belt guided through an upstream web take-up
site to the infeed zone,
whereby the web is sandwiched between paired belts for substantially the entire path from the take-up site to the output conveyor.
