    • Sewing machinery for fabric webs, in which the fabric web is supported over its whole width on a base plate arranged between two deflection pulleys, has stretchers arranged on both sides of the fabric web that continuously stretch the fabric web in the transverse direction of its length and that engage its pileless zones. Edge folding devices mounted on the base plate on both sides of the fabric web each have a sewing machine for sewing the folded edges. A pair of motor-driven rollers engage the longitudinal edges of the fabric web over all its length. In order to improve such a hemming device so that folds do not disrupt the formation of the hem and that the edge folding devices are not affected by the various thicknesses of different sections of the fabric web that is to be hemmed, the edge folding device is formed of a system of elastic guiding elements arranged one after the other in the direction of passage of the fabric to be sewed, such as a straightening runner (2), a surface metal sheet (3), several guiding blocks (4), a guide bar (5), a guide rail (6), a guide finger (7), a hemming element (8), an upper hem cover (9), and upper and lower holding tongues (10', 10'').
    • 织物网的缝纫机械,其中织物幅材在布置在两个挠性带轮之间的底板上以整个宽度被支撑在织物幅材的两侧,布置在织物幅材的两侧沿其长度的横向连续地拉伸织物幅材 并且它的无桩区域。 安装在织物两侧的基板上的边缘折叠装置均具有用于缝合折叠边缘的缝纫机。 一对电动滚筒在其整个长度上接合织物幅材的纵向边缘。 为了改进这种折边装置,折叠不会破坏边缘的形成,并且边缘折叠装置不受要被卷绕的织物幅的不同部分的各种厚度的影响,所以边缘折叠装置是 由如下方式构成的弹性引导元件系统:如矫正滑轮(2),表面金属片(3),多个引导块(4),一个导向块 引导杆(5),导轨(6),引导指(7),折边元件(8),上折边盖(9)以及上下固定舌片(10',10“)。

    • The aim of the invention is to provide a method of hemming a continuous strip of textile fabric which is conveyed by an edge-folding device and whose hem is subsequently sewn to give an accurate hem even if the zone used to form the hem is distorted with respect to the rest of the strip of fabric. To achieve this, the invention proposes that the strip of fabric is conveyed through the edge-folding device to the sewing device at constant speed and the edge used to form the hem is conveyed by the edge-folding device at a speed which is different from that of the rest of the strip as it enters the edge-folding device, at the same speed as it passes through the edge-folding device and at a different speed again towards the end of its passage through the edge-folding device, the speed of the edge relative to that of the rest of the strip being controlled in such a way that any differences in width between the edge zone and the rest of the strip at the entry into and exit from the edge-folding device are compensated for.

    • Steel bit bodies are manufactured in a production process that employs polystyrene patterns in a lost foam casting process. The patterns are machined to permit the formation of complex shapes that cannot be reproduced in simple patterns that are extractable from reusable, two-piece pattern molds or dies. The patterns are machined from a billet material according to a basic, programmed, five-axis machining process to form multiple copies of a reproducible complex pattern body. The process is modified to produce multiple copies of a modified design. Machining the complex patterns and producing variations by changing the machine program permit multiple bit patterns of variable forms to be produced without need for building an intermediate, reusable pattern mold that would require multiple mold pieces, thus eliminating the associated time and expense required in the creation of a new pattern mold for each variation of the bit design. The pattern is machined in a single chucking operation in a machine tool adapted for machining plastics in a three-dimensional global process. The plastic has a composition and a density that permit it to be machined into a pattern having relatively small, unsupported structural projections and smooth surface features. Bit patterns formed in the process have forward canted blades that are machined from mating planar surfaces to simplify the machining process. The edges of the forward canted blades form a spiral surface for mounting cutter elements. The forward canting makes the blades stronger and thus permits the blades to be thinner than non-canted blades to increase the clearance between blades, which improves the movement of cuttings past the bit. Recesses are machined into the gauge face of the patterns to produce a recess in the casting for receiving hardfacing. The hardfacing in the recess forms a layer that cooperates with the surrounding blade material to form a smooth transition area as the bit wears during usage.
    • 在生产过程中制造钢钻头体,在生产过程中采用聚苯乙烯模型进行失蜡铸造。 这些图案被加工成允许形成不能以可重复使用的两件式图案模具或模具提取的简单图案再现的复杂形状。 根据基本的,编程的五轴加工工艺,从坯料材料加工图案,以形成可复制的复合图案体的多个副本。 该过程被修改以产生经修改的设计的多个副本。 通过改变机器程序来加工复杂图案并产生变化,可以生产多种可变形式的位图形,而不需要构建需要多个模具件的中间的可重复使用的图案模具,从而消除了创建中所需的相关时间和费用 的一个新的模式模具的每一个变化的位设计。 该模式在适用于在三维全局过程中加工塑料的机床中的单次夹紧操作中加工。 该塑料具有允许其被加工成具有相对小的,无支撑的结构突起和光滑表面特征的图案的组成和密度。 在该过程中形成的钻头图案具有从配合的平面加工的前刀片,以简化加工过程。 前倾叶片的边缘形成用于安装切割器元件的螺旋表面。 前倾倾斜使得叶片更坚固,从而允许叶片比非斜叶片更薄以增加叶片之间的间隙,这改善了切屑通过钻头的运动。 凹槽被加工到图案的表面上,以在铸件中产生用于接收表面硬化的凹部。 凹槽中的表面硬化形成与周围的刀片材料配合的层,以便在使用期间钻头磨损时形成平滑的过渡区域。

    • The edge portion (18) of sheet material moves about a turning plate (65), moving through first and second right angle turns (44 and 45). A turning belt (50) moves in unison with the edge portion (18) through the first two turns, and then moves through third and fourth right angle turns to advance along its return flight. An open ended slot (73) is formed between the first and second right angle turns to allow the turning belt and edge portion to move from beneath the turning plate to above the turning plate, so as to permit the edge portion of the sheet material to always turn in a downward direction as it is being turned over and placed in a folded postion. Folding plate (77) guides the sheet material to help form the fold (20) in the sheet material, and separator plate (76) separates the edge portion (18) of the sheet material fromthe turning belt (50).
    • 板材的边缘部分(18)围绕转板(65)移动,通过第一和第二直角匝(44和45)移动。 转动带(50)通过前两匝与边缘部分(18)一致地移动,然后通过第三和第四直角匝沿其返回飞行前进。 在第一和第二直角匝之间形成有开口的狭槽(73),以使转动带和边缘部分从转向板下方移动到转向板上方,从而允许片材的边缘部分 总是向下转动,因为它被翻转并放置在折叠位置。 折叠板(77)引导片材以帮助形成片材中的折叠(20),并且隔板76将片材的边缘部分(18)与转动带(50)分离。
