Classification: CPC B | IPC B

Claim 11:
12. An apparatus comprising:
an input feed element to receive a web from a first direction and to turn the web to a second direction;
a first feed element to receive the web from the input feed element;
a second feed element to receive the web from the first feed element, wherein the second feed element extends at a common angle as and is parallel to the input feed element; and
a first actuator to move the first feed element;
a second actuator to move the second feed element, wherein the second actuator is separate from the first actuator;
a detector to detect a position of the web;
a controller to:
determine a shift distance at which the web exiting the second feed element has shifted from an intended feed path;
determine a second linear movement distance for the second feed element based on the determined shift distance;
cause the second actuator to move the second feed element the determined second linear movement distance; and
cause the first actuator to move the first feed element a first linear movement distance, the first linear movement distance differing from the second linear movement distance, wherein the second feed element is at a fixed angle relative to the first feed element and wherein the first actuator is to move the first feed element at a different rate at which the second actuator is to move the second feed element, so that the first feed element reaches the first linear movement distance concurrently with the second feed element reaching the second linear movement distance.
