A placement apparatus comprising an anvil roller, a die roller communicatively associated with the anvil roller, and a bump transfer roller communicatively associated with the vacuum roll. The invention also provides a process for placing articles on a web, comprising the steps of providing a stream of articles, placing the articles on the anvil roller, moving the anvil roller, moving an output web, and periodically bringing the output web into communicative association with the anvil roller whereby the articles are transferred to the output web at a predetermined distance from each other.

1. A method for using a placement apparatus to place articles on a web, wherein the placement apparatus includes a frame with a die roller, an anvil roller, a bump transfer roll assembly with a bump transfer roll, the method comprising: passing a first web between the die roller and the anvil roller
1. A method for using a placement apparatus to place articles on a web, wherein the placement apparatus includes a frame with a die roller, an anvil roller, a bump transfer roll assembly with a bump transfer roll, the method comprising: passing a first web between the die roller and the anvil roller of the web placement module;passing a second web between the anvil roller and the bump transfer roll;cutting the first web using the anvil roller and the die roller to provide cut articles;transferring the cut articles to the second web using the anvil roller; andplacing the cut articles on the second web using the bump transfer roll assembly, a motor and mechanical linkage between the motor and the bump transfer roll which includes an eccentric shaft, wherein the mechanical linkage includes an eccentric shaft, and wherein placing articles on the second web using the bump transfer roll includes using the motor to rotate the eccentric shaft of the mechanical linkage to periodically move a bump transfer roll toward the anvil roll, and wherein placing articles on the second web using the bump transfer roll includes using a knob to manually rotate the eccentric shaft of the bump transfer roll to adjust the position of the bump transfer roll. 2. The method of claim 1, further comprising moving the first web and the second web concurrently as the first web is cut and as the cut articles are transferred to and placed on the second web, wherein moving the first web and the second web concurrently includes: moving the first web at a first predetermined velocity; andmoving the second web at a second predetermined velocity. 3. The method of claim 2, wherein the first predetermined velocity is less than the second predetermined velocity. 4. The method of claim 2 wherein the first predetermined velocity is equal to the second predetermined velocity. 5. The method of claim 1, wherein cutting the first web transforms the first web into a first web matrix, and wherein the method further includes collecting the first web matrix after the first web passes between the anvil roller and the die roller. 6. The method of claim 1, comprising: providing a stream of the articles on the first web and moving the second web, wherein transferring the cut articles includes placing the articles on an anvil roller and rotating the anvil roller;as the anvil roller rotates and the second web moves, intermittently bringing the second web into communicative association with the rotating anvil roller to transfer the articles from the rotating anvil roller to the moving second web, moving the bump transfer roll translationally from a first position away from the anvil roller to a second position toward the anvil roller to intermittently bump the second web toward the anvil roller; and rotating the eccentric shaft of the bump transfer roller to adjust the second position of the translational motion. 7. The method of claim 1, wherein the articles are spaced on the second web at a predetermined distance from each other. 8. The method of claim 6, wherein the motor is a servo motor, and moving the bump transfer roll to intermittently bump the second web toward the anvil roller further includes using the servo motor to control motion of the bump transfer roll between a first axial position and a second axial position. 9. The method of claim 1, wherein the frame has at least one clamp, the method further comprising using the at least one clamp to mount the placement apparatus to a web processing machine. 10. The method of claim 1, wherein the placement apparatus includes an input nip station having a servo drive nip roller and an idler nip roller, the method comprising threading a first web through the input nip station of the placement apparatus.
