    • An apparatus is arranged to successively make plastic bags each of which has a shape of circumference. The apparatus comprises web feeding means by which a web material is intermittently fed for a length along a longitudinal feeding path. The web material comprises two or more layers of plastic film. Web cutting means is disposed along the feeding path. The web cutting means has a shape corresponding completely or incompletely to the shape of circumference of plastic bag so that the web material can be cut into the shape of circumference of plastic bag by the web cutting means whenever the web material is intermittently fed and temporarily stopped, to successively make the plastic bags with a waste kept continuous. The web cutting means comprises partially cutting means. The plastic bag has an upstream edge along which the web material is partially cut by the partially cutting means so that the plastic bag can be kept connected with the waste at the upstream edge of plastic bag. Drawing means is disposed downstream of the cutting means. The waste is diverged from the plastic bag, directed to and drawn by the drawing means after the web material is cut. Discharge means is disposed downstream of the cutting means. The plastic bag is directed to the discharge means without the waste. The plastic bag is then pulled by the discharge means to be torn from the waste at the upstream edge of plastic bag. The plastic bag is then discharged by the discharge means.
    • 设置有连续地制造塑料袋,每个塑料袋都具有周长的形状。 该装置包括纸幅馈送装置,通过该纸幅馈送装置,沿着纵向馈送路径间歇地馈送幅材材料一段长度。 纤维网材料包括两层或更多层塑料膜。 纱线切割装置沿着进给路径设置。 卷筒纸切割装置具有与塑料袋的周边形状完全或不完全相同的形状,使得每当纸幅材料被间歇地进给并暂时停止时,可通过卷筒纸切割装置将卷筒纸材料切割成塑料袋的圆周形状 ,连续使废塑料袋保持连续。 卷筒纸切割装置包括部分切割装置。 塑料袋具有上游边缘,通过部分切割装置部分地切割网状材料,使得塑料袋可以在塑料袋的上游边缘处与废物保持连接。 拉拔装置设置在切割装置的下游。 在卷材材料切割后,废物从塑料袋中分离出来,指向并由拉丝装置拉出。 排出装置设置在切割装置的下游。 塑料袋被引导到排放装置而没有浪费。 然后,塑料袋被排出装置拉出,以从塑料袋上游边缘处的废物中撕开。 然后,塑料袋通过排出装置排出。

    • A punching device for punching an edge of an oval subject to make a pattern includes a jig having a pattern hole with a predetermined pattern and supplied with the subject to be patterned; a punching member having a punch pin corresponding to the pattern hole so as to form a punching pattern by punching an edge of the subject supplied to the jig; and a base on which the jig and the punching member are coupled, the base giving a base surface on which the subject to be punched is supplied, wherein the base includes: a rotation guide projection (21) for guiding an edge of the oval subject with the same curvature as the edge when the subject is rotating; a positioning guide projection (22) for setting an initial position of the subject together with at least a part of the rotation guide projection so that an initial punching region of the oval subject is punched; and a criterion marking (24) having the same pattern as the pattern of the pattern hole or formed as a part of the pattern so as to set a rotating angle of the oval subject so that the punching pattern is successively formed.
    • 用于冲压椭圆形物体的边缘以形成图案的冲压装置包括具有预定图案的图案孔的夹具,并供给待图案化的对象; 冲压构件,其具有与图案孔相对应的冲头针,以便通过冲压供给夹具的被检体的边缘来形成冲压图案; 以及夹具和冲孔构件联接在其上的基座,所述基座提供被供给被检体的基部表面,其中所述基部包括:用于引导所述椭圆形物体的边缘的旋转引导突起(21) 当被摄体旋转时具有与边缘相同的曲率; 定位引导突起(22),用于将所述被摄体的初始位置与所述旋转引导突起的至少一部分一起设置,使得所述椭圆形物体的初始冲压区域被冲压; 以及标准标记(24),其具有与图案孔的图案相同的图案或形成为图案的一部分,以便设定椭圆形物体的旋转角度,使得连续形成冲孔图案。
