A cross lapper for laying a fleece from a card web includes a laying carriage movable transversely with respect to an output conveyor belt above same, and an upper carriage as well as a plurality of card web transport belts for passing the card web through the upper carriage and the laying carriage into an output nip formed at the laying carriage, wherein a belt entrance with a downwardly inclined entrance zone is formed at the upper carriage through which a first card web transport belt is passed, which extends from a lower end of the entrance zone in the direction towards the laying carriage, and is accompanied in parallel in this section by a section of a second card web transport belt enclosing the card web together with this belt up to the laying carriage. The second card web transport belt leaving the laying carriage and guided back to same extends through a tensioning carriage only which is movable transversely with respect to the output conveyor belt, but is not passed through the upper carriage.
A cross lapper for laying a fleece from a card web, said cross lapper including a laying carriage (3) movable on rails in a machine stand transversely to an output conveyor belt (1) above same and an upper carriage (18) movable in the machine stand transversely to said output conveyor belt on rails as well, and a plurality of card web transport belts for guiding the card web through the upper carriage and the laying carriage into a discharge nip formed at the laying carriage, wherein a belt entrance with a downwardly inclined entrance zone is formed at the upper carriage, through which a first card web transport belt is passed, which extends from a lower end of the entrance zone in a section towards the laying carriage, and is accompanied in parallel in this section by a section of a second card web transport belt enclosing the card web together with same until the laying carriage, and is guided back through the laying carriage as a cover belt over the output conveyor belt and in parallel thereto towards the laying carriage, wherein a section of the second card web transport belt guided back to the laying carriage is passed through a tensioning carriage only which is movable transversely with respect to the output conveyor belt, said second card web transport belt bypassing said upper carriage (18).
A cross lapper for laying a fleece from a card web, said cross lapper including a laying carriage movable on rails in a machine stand transversely with respect to an output conveyor belt above same and an upper carriage movable in the machine stand transversely to said output conveyor belt on rails as well, and two card web transport belts for guiding the card web through the upper carriage and the laying carriage into a discharge nip formed at the laying carriage, wherein a belt entrance with a downwardly inclined entrance zone is formed at the upper carriage, and a first card web transport belt extending over the upper carriage is guided through the laying carriage and transversely over the output conveyor belt and through a first tensioning carriage back to the belt entrance, and a second card web transport belt is passed through the laying carriage, said second card web transport belt having an upper part extending in parallel and at a close distance to a section of the first card web transport belt extending from a lower end of the belt entrance in a direction towards the laying carriage, said second card web transport belt further comprising a lower part extending in a same plane as a section of the first card web transport belt leaving the laying carriage, wherein a section of the second card web transport belt returning from the laying carriage in a direction towards the lower end of the belt entrance is passed through a second tensioning carriage only which is movable transversely with respect to the output conveyor belt, said second card web transport belt being not passed through the upper carriage but is bypassing same.
