Apparatus for Perforating a Web Material

摘要

A perforating apparatus has a first roll and a second roll, each being operatively engageable with a support. The first roll has a first longitudinal axis about which the first roll rotates and a first anvil disposed on the first roll and having a first design. The second roll has a second longitudinal axis about which the second roll rotates. A second anvil is disposed on the second roll. The second anvil has a second design. At least one blade is disposed on the support so as to cooperate in interacting relationship with one of the first anvil and the second anvil when the support is operatively engaged with the one of the first anvil and the second anvil. The apparatus comprises two alternative paths for the web material.

1. An apparatus for perforating web material, the apparatus comprising:
a first roll comprising a first longitudinal axis and a first anvil disposed on the first roll, the first anvil having a first design, wherein the first roll rotates about the first longitudinal axis; a second roll comprising a second longitudinal axis and a second anvil disposed on the second roll, the second anvil having a second design, wherein the second roll rotates about the second longitudinal axis; a support operatively engageable with the first roll and operatively engageable with the second roll; and at least one blade disposed on the support so as to cooperate in interacting relationship with one of the first anvil and the second anvil when the support is operatively engaged with the one of the first anvil and the second anvil; wherein the apparatus comprises two alternative paths for the web material, a first path between the first roll and the support and a second path between the second roll and the support, such that in operation the one of the first anvil and the second anvil rotates and interacts with the blade, with the web material being perforated as the web material passes between the blade and the one of the first anvil and second anvil.
