    摘要： A perforating apparatus including: a blade support having a blade support assembly, where the blade support assembly includes: a clamp coupled to the blade support; a blade positioned between the clamp and an outer surface of the blade support; and a plurality of dampener members extending along at least a portion of a longitudinal length of the blade, where a first dampener member is positioned on a first side of the blade, where a second dampener member is positioned on a second side of the blade, and where the first side of the blade faces the blade support and the second side of the blade is opposite the first side of the blade. Also disclosed is a method for forming a line of weakness in a substrate. Also disclosed is a blade support having a corresponding blade support assembly.

    摘要： The present disclosure relates to apparatuses and methods for adjusting and maintaining a position of cutting surfaces used to create lines of weakness in rolled products. During cutting operations, intermittent contact between cutting surfaces causes cutting components to become heated, which in turn, causes an overlap distance between cutting surfaces to vary from desired values. Conversely, when cutting operations are stopped, the components cool, which in turn, may cause the overlap distance to vary from desired values at steady state operating conditions. To help reduce or eliminate the changes to overlap distances caused by cyclical heating and cooling between times of cutting operations and shutdowns, one or more heaters may be utilized to apply heat to one or more components to maintain relatively constant temperatures during periods of cutting operations and/or when cutting operations are paused or stopped. In turn, the heater(s) may operate to maintain and/or change the overlap distance to desired values.
