摘要： Apparatus for looping the free end portions of the outermost convolutions of helical binders which are threaded through the perforations of a stack of loose leaves has a pivotable tool with a cutting edge which clips the end convolution of a properly located binder and a bending edge which bends the free end portion of the clipped end convolution over the neighboring convolution. A rotary loop forming device is thereupon actuated by a lever to convert the deformed end portion into a loop which surrounds the neighboring convolution. The loop forming device has a guide face which cooperates with a parallel second guide face provided on a reciprocable hold-down device which is caused to extend between the end convolution and the neighboring convolution while the end portion is converted into a loop. These guide faces cooperate with a guide face of a locating projection for the binder and with a guide face of the tool to define a channel which confines the end portion during loop forming so that the loop is located in a plane which includes the axis of the binder. The hold-down device has a notch which receives and prevents deformation of the remaining part of the outermost convolution while the free end portion is being looped around the neighboring convolution.

摘要： A web of undulate wire is converted into a series of coherent C-shaped binders of the type known by the trademark Wire-O and used to bind stacks of paper sheets or the like in the making of steno pads, brochures, calendars and similar stationery products by continuously moving the web lengthwise at a constant or variable speed, by imparting to successive increments of one marginal portion of the moving web a concavo-convex shape in stepwise fashion so that the one marginal portion resembles (in cross-section) one-half of the letter C, and by thereupon imparting to successive increments of the other marginal portion of the moving web a concavo-convex shape in stepwise fashion so that the thus converted other marginal portion becomes a mirror image of the converted one marginal portion. The imparting steps include deforming the respective marginal portions from the inner toward the outer edges thereof.

摘要： A machine which converts a strand of wire into a body of meandering shape has two carriers which rotate about parallel axes and respectively carry annuli of pins. One annulus of pins surrounds the other annulus of pins, and each pin of one annulus is adjacent to a pin of the other annulus. When the carriers rotate, neighboring pins of the two annuli move toward each other during one-half of each orbital movement about the respective axes and away from each other during the other half of each orbital movement. A looping device winds the wire alternately about the oncoming pins of the inner and outer annuli while the neighboring pins move away from each other whereby the wire is converted into a meandering body and the wire portions between successive pins are stretched to assume a predetermined shape. The meandering body is stripped off the pins while the neighboring pins move nearer to each other. The meandering body can be used as a starting material for binders which connect the sheets of note books, calendars or the like.
