Such wire is generally wound on a cylindrical tube or spool made of cardboard or some other suitable material weighing 50 to 500 kg. «Such wire packages are usually sold as a unit _? the most commonly used weight being 100 kg.

The object of the invention is it _? to create a simple device for unwinding metal wire, which makes it safe to use on the one hand the commercially available wire package without change in the unwinding device or to connect this package firmly to an assemblable unwinding device «) Another task is to make this unwinding device to be provided with suitable control devices for the unwinding of the wire

According to the invention, in a device for unwinding rolls of metal wire _? especially additional metal

wire rolls for seam welding machines j the wire roll in two flanges made of metal, plastic or the like _{that can be placed on the end faces of the spool 9} which are connected to one another by means of an unwinding axis protruding through the interior of the wire roll and with a foldable handle attached to this axis for pressing the flanges together are provided.

In a preferred embodiment, the Abspulachse is at its free end with a thread od _or the like "equipped j by the axis can be fixed in a flange" is further arranged so formed ugd in a preferred embodiment, the handle that by simply folding over the Flanges pressed against the end faces of the coil and thus grounded.

According to a further preferred embodiment of the In accordance with the invention, the device is provided with an unwinding arm which is preferably bent by 90, the lower part of which

stretched to the side of the device and an adjustable one with in the l-depth of its lower end a guide roller provided with a circumferential groove for guiding the wire. In this case, "in the preferred embodiment a movable guide sleeve can be provided on the axis common to the guide roller In addition, in a further preferred embodiment, the Abspularm carries in the amount of its bend another upper guide roller that carries the wire of the feed roller of a machine, such as welding machine forwarded "

has a wire package 1, which is formed as usual Verkaufspacicung and a coil 2 _S on which the I-Ietall'j.raht wound machine-like. "" On either side of this wire package 1, a lower Plansch 3 and an upper flange. 4 are provided, which each have a ring 5 on the inside, which fits into the free space of the wire package _9, i.e. the interior of the hollow coil 2. The two flanges 3 and 4 are held together by an axle 10 which press the two flanges together by means of threads and contact surfaces .

The wire roll is attached to the unwinding device as follows;

The unit consisting of the cardboard core or reel 2 and the wire package 1 wound on it becomes on the lower flange lying on the floor 3

concentrically mounted by paying attention to _two that this unity to the existing ring or sand bar 5 closely matches with the Plansch 3 in one piece ""! This placement must necessarily so done _s that a mounted on the wrapping paper of the wire package one arrow in a counterclockwise direction shows “The upper flange 4 is then placed on top of the wire package 1, indent

one he is also centered with the help of the ring 5 made of / piece with the puddle 4 Rings 5 formed recesses 8 (see Pig »3) coincide} d. h _# are brought into congruence with them »In order to firmly connect the two planes 3 and 4 with the wire bundle they hold, the axis 10 of the unwinding arm 22 is inserted into the central opening 9 of the upper planch. 4 so that the The threaded end of the axle 10 protrudes through the central hollow Earton core or spool 2 and with the also threaded end in the middle of the lower one

Flange 3 formed bore 12 (Figo 1 and 2) comes into engagement z "B _{0 is} screwed with her * The pressing of the flanges 3 and 4 against the cardboard core or reel is done without effort and without special" tools by the at the upper end of the axis 10 (Figo 1) attached handle 13 folds.

In addition to an annular rim 5 is when exported ungs form according to the invention an additional annular edge strip 6 (Fig »3) is provided, which in advantageous wise the contact pressure is locally limited to the cardboard core from which the core or coil of the wire roll is educated "

¹ Ten the clamping of the carton or from the soul, "-spule 2 and the wire 1 existing packet unit between the flanges 3 and 4 by means of the axle 10 and of the handle is done by cutting through the sheet-metal strip 7 _S binding

which can then be easily removed due to the recesses 8 provided in the rings 5 »

Jie aside from being wrapped around by the metal strips Wire mass expands and rests against flanges 3 and 4 of the coil *

The device for unwinding the metallic wire coil is shown in Figures 1 and 4 ;, while details of this apparatus are illustrated in Figures 5 ₉ 6 and 7 _S "This unwinding device consists mainly of a bent or" kinked Abspularm 22 ₉ whose lower portion extends laterally from the the above-identified parts 1,2,3 and 4 unit formed "This Abspul- or guide arm carries near its lower end a provided with a movable guide 15 _$ a circumferential groove having the guide roller 14 'This guide arm 90 ° bent or kinked so that it is horizontal above the upper flange 4

zontally runs parallel to it »The end of its horizontal Port setting 22 is fastened in a bushing 31 which is held by means of ball bearings 32 so that it is around the upper stump of axis 10 (s, Figo 7) is rotatable « In the following there are still further details of the Abs "pulVorrichtung exposed.

The threading of the additional seam _? to feed it to the welding machine, proceed as follows

One takes the free end of the wire and feeds _it} after it has been threaded into the mounted on the same axis as the guide roller 14 movable guide (guide sleeve) 15 (from the bottom) on the lower guide roller 14 '

Then the wire is passed over the upper guide roller and finally to the welding machine.

listening feed roller 17 ₅ whose outer circumference, which is in contact with the wire, is tangent to the imaginary axis line of the central axis of the roller 1 _S 2. The wire is held in the circumferential grooves of the guide rollers 14 and 16 by rollers 18 and 19 respectively arranged in these grooves.

The advantage of the guide arm 22-22 'is extremely reduced distance from the pick-up point for the Wire through the arm from the surface of the wire roll layer “This is possible thanks to the movable guide (guide sleeve) 15, which ensures the correct entry of the wire in the leadership role 14? even when using pretty high coils of wire. The position of the guide roller 14 can be based on its at the end 21 of the Abspularmes 22 (Fig. 4) to optimally adjust the attached swivel bracket. This holder 20 can be through Tighten the screw 23, d. h # unadjustable do.

The unwinding device according to the invention is provided with a brake which is designed so that they both allows slow as well as fast unwinding.

This brake also has its own braking device 33 a device 34 for balancing the centrifugal force. These two devices are shown in FIGS. 1, 5 and 6 shown.

When unwinding slowly, for example at one speed of 20 m / min. is the centrifugal force aimed? lift arm 22 (Pig. 5) upwards, so that the pressure of the brake shoe 24 (Fig. 5) on the with the upper flange 4 (Fig. 1) firmly connected brake or Friction disk 25 is reduced. In this case, the centrifugal force is caused by the pressure of the helical spring 26 balanced against a stop 27, both of which are housed in the housing 29. Lifts when stopping the centrifugal force on, so that maximum braking

is brought about.

When unwinding quickly, for example at one speed of 200 m / min., the braking force (intensity) must be high so that the brake shoe 24 with the Surface of the brake disc 25 in firm, intense contact must stand. This is achieved by placing the cap 28 (Fig. 6) of the spring 26 against the bottom of its female Housing 29 defines and the braking force is set by the clamping intensity of the screw 30.

The wear of the brake shoe 24 can be readjusted or »compensated» with the help of the screw 31 (Fig. 5)

An additional special feature of the embodiment described and illustrated lies in the fact that the arm 22 can be used as a handle which enables the wire spool to roll on the floor when one
