APPARATUS FOR CORRUGATING MATERIALS

摘要

An apparatus (10) for corrugating material includes an upper shaft (12) rotating about a first longitudinal axis and a lower shaft (16) rotating about a second longitudinal axis. Either the upper shaft (12), the lower shaft (16), or both shafts are constructed of a flexible material. At least one upper corrugation roll (20) is secured to the upper shaft (12), and at least one lower corrugation roll (22) is secured to the lower shaft (16). The upper corrugation roll (20) and the lower corrugation roll (22) are interspersed relative to each other and spaced such that the material is fed between the upper (20) and the lower (22) corrugation rolls to corrugate the material. Materials of varying rigidities may be passed between the upper (20) and lower (22) corrugation rolls such that lighter weight material (24) is corrugated while heavier weight material (26) deflects the flexible shaft or shafts to reduce corrugation.
