Claim 4

The invention according to claim 1 wherein said movable processing means comprises a pair of opposed engageable rollers through which the web is transported, said rollers having a roughened web engaging surface.

Claim 5

The invention according to claim 1 wherein said controlling means comprises a reversible motor drivingly connected to said movable processing means, a reversing switch for said motor, and means for actuating said reversing switch.

Claim 6

The invention according to claim 4 wherein said actuating means comprises a cam connected to said switch, and a timer motor for driving said cam.

Claim 7

In a processing device having first and second processing stations, and means for transporting a web through the stations in one direction and in succession for processing the web, the combination comprising: first means at the first station having a web engaging portion movable in the direction of web transport for engaging and processing the web as it is transported therethrough; second means at the second station having a web engaging portion movable in the opposite direction of web transport for engaging and processing the web as it is transported therethrough; and means coupled to said first and second processing means for reversing the direction of mOvement of said first and second processing means in timed relation during transport of the web whereby when said portions of said first and second processing means engage the leading end of the web they are moving in the direction of web transport, and when said portions of said first and second processing means engage the trailing end of the web they are moving in the opposite direction of web transport.

Claim 8

In a processing device having first and second processing stations, and means for transporting a web through the stations in one direction and in succession for processing the web, the combination comprising: first means at the first station having a web engaging portion movable in the direction of web transport for engaging and processing the web as it is transported therethrough; second means at the second station having a web engaging portion movable in the opposite direction of web transport for engaging and processing the web as it is transported therethrough; and means coupled to said first and second processing means for reversing the direction of mOvement of said first and second processing means in timed relation during transport of the web whereby when said portions of said first and second processing means engage the leading end of the web they are moving in the direction of web transport, and when said portions of said first and second processing means engage the trailing end of the web they are moving in the opposite direction of web transport.

Claim 9

The invention according to claim 6 wherein said reversing means comprises a reversible motor drivingly connected to said first and second processing means, a reversing switch for said motor, and means for actuating said reversing switch.

Claim 10

The invention according to claim 7 wherein said actuating means comprises a cam connected to said switch, and a timer motor for driving said cam.

Claim 11

The invention according to claim 6 wherein said web transporting means comprises a transport motor, and transport rollers including entrance transport rollers driven by said transport motor; said reversing means comprises a reversible motor drivingly connected to said first and second processing means, a reversing switch for said reversible motor, a cam connected to said reversing switch, and a timer motor for driving said cam; said transporting means further having a clutch interconnecting said entrance transport rollers to said transport motor, and a clutch switch for said clutch actuable by said cam in timed relation to the transport of the web for disabling said entrance transport rollers to prevent the introduction of another web into the processing device until said entrance transport rollers are enabled.
