Abstract
Abstract A machine for crosswise deposition of carded webs and the like which are advanced on a feeder belt onto a continuously driven discharge belt. This latter belt is positioned below the feeder belt and travels in a direction essentially at right angles to the direction of movement of the feeder belt. The machine also comprises two conveyor belts interposed between the feeder belt and the discharge belt and these two belts are driven at the same speed and at a constant tension. Means are provided to advance the carded web on these conveyor belts under forced guidance such that said carded web is deposited on the discharge belt evenly and without formation of folds.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
An improved machine for crosswise deposition of carded webs advanced on a feeder belt, onto a continuously driven discharge belt which is positioned below the feeder belt and travels in a direction which is essentially at right angles to the direction of movement of the feeder belt, said machine comprising two conveyor belts for the carded web, these conveyor belts being arranged between said feeder belt and the discharge belt, an outlet opening for the carded web, said opening being provided on a first travelling carriage which is adapted to be displaced in a reciprocating manner over the discharge belt in the transverse direction of the latter, and a second travelling carriage, wherein the improvement comprises adapting the two conveyor belts to be driven at the same speed, an inlet opening formed between the conveyor belts, said inlet opening being arranged to be stationary beneath the outlet end of the feeder belt, means for running the two conveyor belts over pulleys on said first carriage on which said outlet opening is provided and means for adapting said second carriage to be displaced in such a direction and at such a speed relatively the first carriage that the two conveyor belts are held under a constant tension.

An improved machine for crosswise deposition of carded webs advanced on a feeder belt, onto a continuously driven discharge belt which is positioned below the feeder belt and travels in a direction which is essentially at right angles to the direction of movement of the feeder belt, said machine comprising two conveyor belts for the carded web, these conveyor belts being arranged between said feeder belt and the discharge belt, an outlet opening for the carded web, said opening being provided on a first travelling carriage which is adapted to be displaced in a reciprocating manner over the discharge belt in the transverse direction of the latter, and a second travelling carriage, wherein the improvement comprises adapting the two conveyor belts to be driven at the same speed, an inlet opening formed between the conveyor belts, said inlet opening being arranged to be stationary beneath the outlet end of the feeder belt, means for running the two conveyor belts over pulleys on said first carriage on which said outlet opening is provided and means for adapting said second carriage to be displaced in such a direction and at such a speed relatively the first carriage that the two conveyor belts are held under a constant tension.
Claim 3
Dependent Claim
51 words
An improved machine in accordance with claim 1, wherein the improvement comprises arranging the carriage supporting the outlet end of the conveyor belts for connection in a manner known per se alternatively to one or the other run of a belt or similar endless transmission means running over two pulley wheels.
Claim 4
Dependent Claim
91 words
An improved machine in accordance with claim 2, wherein a clutch comprises a pneumatically operated piston in a cylinder in which said piston is adapted to move in a reciprocating manner, said piston being provided at both its ends with a clamping shoe which cooperates with a fixed abutment on the first carriage and is adapted to clamp the belt run in question against the associated abutment when the piston is axially displaced and thus connect said carriage to the belt run in question travelling between the shoe and the abutment.
Claim 5
Dependent Claim
72 words
An improved machine in accordance with claim 1, wherein the mutual speeds and directions of movement of the carriages ad are adjusted by a wire or the like, said wire being attached to the carriage controlling the outlet end of the conveyor belts and travelling in a manner known per se over a number of pulleys On the machine frame and said second carriage to an attachment point on the machine frame.
