Abstract
A device for forming a groove in a cover, the device including a circular score anvil having a first axis and being rotatable in a first direction and a circular scoring knife having a second axis positioned parallel to the first axis and arranged radially opposite the circular score anvil to define a gap between the score anvil and the scoring knife. The scoring knife is rotatable in a second direction opposite to the first direction and comprises a scoring element having an edge region that is tapered to form a ridge toward a periphery of the element. The edge region includes an intermediate space that divides the edge region into two spaced apart knife edges. A groove is formed in the cover while moving through the gap by operative cooperation of the scoring knife and score anvil.
