An apparatus for forming a layered, cross-lapped web of predetermined width from a strip of batt material is disclosed. The apparatus comprises a pair of transversely spaced frame members, a delivery conveyor having a web support surface thereon positioned between the frame members and movable longitudinally relative thereto, a cross-lapping carriage transversely reciprocatively movable relative to the delivery conveyor and adapted to deliver the strip of batt material to the support surface to form the layered cross-lapped web on the delivery conveyor, and shielding aprons carried by the cross-lapping carriage and statically juxtaposed above the layered web for shielding portions of the web adjacent to the cross-lapping carriage from air eddies caused by the transverse reciprocative movement of the cross-lapping carriage. The shielding aprons have variable length portions thereof extending from each side of the cross-lapping carriage to corresponding ones of the frame members during the transversely reciprocative movements of the cross-lapping carriage and they have essentially zero transverse movement relative to the portions of the layered web positioned therebeneath.
Apparatus for forming a layered, cross-lapped web of predetermined width from a strip of web material, comprising a pair of transversely spaced frame members, conveyor means having a web support surface positioned between said frame members and movable longitudinally relative thereto, cross-lapping means transversely reciprocatively movable relative to said conveyor means and adapted to deliver said strip of web material to said web support surface to form said layered cross-lapped web on said conveyor means, and apron means carried by said cross-lapping means and juxtaposed above said layered web for shielding portions of said web adjacent to said cross-lapping means from air eddies caused by said transverse reciprocative movement of said cross-lapping means, said apron means having variable length portions thereof extending from each side of said cross-lapping means toward corresponding ones of said frame members during the transverse reciprocative movements of said cross-lapping means, said variable length portions each having essentially zero transverse movement relative to the portions of said layered web positioned therebeneath.
