    • A cutting device for a roll of material wherein a cutter bar with a cutting blade fixed thereto is arranged between two upright posts. To cut the material from the roll a length of material is withdrawn from beneath the cutter bar and lifted against the cutter bar. The cutter bar is allowed to pivot about a longitudinal axis until an upstanding rib and a notch in the cutter bar clamp the upright posts between them and lock the cutter bar against further pivoting motion. The material is then torn across the cutting blade since the cutter bar cannot be further pivoted.
    • 一种用于一卷材料的切割装置,其中具有固定到其上的切割刀片的切割杆布置在两个立柱之间。 为了从辊中切割材料,一段材料从切割器杆下方被抽出并且被提升到切割杆上。 允许切割杆围绕纵向轴线枢转,直到直立肋和切割杆中的切口将它们之间的立柱夹紧并锁定刀具杆以防止进一步的枢转运动。 然后,由于切割杆不能进一步枢转,因此材料被切割穿过切割刀片。
