    • A process is disclosed for cutting a strip (16) of plastically deformable material transported on a series of chases (20) into individual shaped pieces (14, 32). In a cutting station (10), a first shaped piece (14) is cut off from the strip (16) by a first cut at its top edge (26), and the bottom edge (36) of the first shaped piece (14) is shaped in a shaping station (12). In order to develop a process that allows shaped pieces to be cut off from the strip with fully rounded or chamfered edges, an upset-free surface and burr-free edges, the first cut is slanted in relation to the vertical transverse plane (24) of the strip (16), so that a slanted material excess (34) results at the top edge (26) of the first shaped piece (14) and a slanted cut (28) results at the strip (16) and forms the bottom edge (30) of the following shaped piece (32). The material excess (34) at the top edge (26) of the first shaped piece (14) is cut off during a second cutting operation.
    • 本发明涉及一种用于切割上子模的一条链塑性可变形材料成各个异型件(20)传送的磁带(16)(14,32),其特征在于,在切割站(10)包括通过第一接头(14) 发生在其头部侧边缘(26)首先从带切(16)被切断,在第一模具件的脚侧边缘(36)的一模制站(12)形成(14)。 以提供其中从所述条形部分在切割完全形成的舍入或倒角,的冷门自由表面和毛刺的自由边缘之一的方法,提出的是,第一切口倾斜于所述带的横向垂直平面(24)(16 ),其中,(在第一模件(14),倾斜切割的头部侧边缘26)(28)形成的倾斜材料悬(34)和(磁带16)上,随后的第二模具件的脚侧边缘(30)(32) 形式,并且所述第一模件(14)的头部侧边缘(26)是可用的材料悬(34)通过一个第二切割切断。
