Abstract:
A cutting mechanism for cutting a flat material web into individual portions as the web travels in a feeding direction from a printing head of a printer, said cutting mechanism comprising:a housing including an entrance section for receiving the traveling flat material web;a cutter disposed relative to said entrance section for transversely severing portions of the traveling flat material web relative to the feeding direction;an exit section in said housing through which severed portions of the web are dispensed from the cutter; andmeans for damping web deflections from shock waves caused by transversely severing portions of the web, said means for damping being constructed and disposed relative to said entrance section to permit free and unimpeded web travel into said entrance section in the feeding direction without imposing a force on said web when said web is in an undeflected condition, wherein said means for damping includes a damping plate having one hinged end such that said damping plate is adapted for pivotal movement in response to deflections caused by shock waves occurring in the flat material, said damping plate being biased into an initial position relative to the flat material web without imposing a force on the web when said web is in an undeflected condition, said damping plate pivoting relative to said hinged connection when said web deflects against said damping plate from the shock waves caused by transversely severing said web.
