Abstract
An apparatus for transporting web material, such as a folded paper web in a web-fed rotary printing press, is disclosed which includes a first nip roller having a first set of driven and non-driven wheels which are arranged side by side along a rotational axis of the first nip roller, and a second nip roller having a second set of driven and non-driven wheels arranged side by side along the rotational axis of the second nip roller. The wheels of the first and second nip rollers are arranged such that the driven wheels of the first roller are facing the non-driven wheels of the second roller, thereby forming a nip for receiving and conveying the material web.
Claims19
Apparatus for transporting web material in a web-fed rotary printing press, comprising:
- a first nip roller having a first set of driven and non-driven wheels arranged side by side along a rotational axis of the first nip roller;
- and
- a second nip roller having a second set of driven and non-driven wheels arranged side by side along a rotational axis of the second nip roller, the wheels of the first and second nip rollers being arranged such that the driven wheels of said first roller face the non-driven wheels of the second roller to form a nip for receiving and conveying the web material.
Web-fed rotary printing press comprising:
- a folder for folding a printed web material;
- a first nip roller having a first set of driven and non-driven wheels arranged side by side along a rotational axis of the first nip roller;
- and
- a second nip roller having a second set of driven and non-driven wheels arranged side by side along a rotational axis of the second nip roller, the wheels of the first and second nip rollers being arranged such that the driven wheels of said first roller face the non-driven wheels of the second roller to form a nip for receiving and conveying the printed web material.
Method for transporting web material in a web-fed rotary printing press while introducing corrugations into the web material, comprising the steps of:
- driving a first nip roller having a first set of driven and non-driven wheels arranged side by side along a rotational axis of the first nip roller;
- and
- driving a second nip roller having a second set of driven and non-driven wheels arranged side by side along a rotational axis of the second nip roller, the wheels of the first and second nip rollers being arranged such that the driven wheels of said first roller face the non-driven wheels of the second roller to form a nip for receiving and conveying the web material, while introducing corrugations to the web material.
