1. A web processing machine in a web production line, comprising:
a frame comprising:
a base,
two vertical stanchions extending upwardly from and rigidly affixed to the base, and
a cross-member rigidly affixed across top most ends of the two vertical stanchions;
a processing assembly comprising:
a yoke rigidly affixed to the cross-member and having opposing vertical side arms;
a process wheel located between and rotatably affixed to the opposing vertical side arms of the yoke, wherein the process wheel includes a first portion having processing features and a second portion, and wherein the first portion has a first diameter and the second portion has a second diameter that is less than the first diameter;
a drive motor connected to the process wheel; and
an anvil roller located between and rotatably affixed to the two vertical stanchions at opposite ends, wherein the process wheel is in close proximity to the anvil roller and spaced apart by a nip having a gap configured to receive a traveling web of flexible material from the web production line such that the web is periodically acted upon by the processing features of the process wheel which intermittently contact the web as the web passes through the nip; and
a motor controller programmed such that the drive motor provides intermittent rotary motion to the processing wheel, the motion of the process wheel defined by repeating 360-degree cycles of rotation, wherein the process wheel stops and starts during every cycle having a run period followed by a stop period that includes a stopped home position of the process wheel where the second portion of the process wheel is adjacent the anvil roller so that the web can pass through the nip without interference from the processing features, wherein the anvil roller is turned in correspondence with the speed of the web apart from the speed of the process wheel.
