The invention relates to wrapping machines for stretching and wrapping ham as well Meat and sausage products with string.

Winding machines for this purpose are already known in which a number around a common Shaft arranged needles picks up the ham and rotates the shaft in a rotating motion be moved. In these winding machines, the needles are attached to a non-adjustable disc, and the ham is impaled on the needles, the only purpose of which is to take away when turning the Have wave.

However, it is necessary to stretch the ham before wrapping, which can be done with these wrapping machines is not reachable. A winding machine is also known in which a number of elastic, towards their free end tapered and radially mutually adjustable hook needles that The entire length of the goods to be wrapped encloses, stretches and holds, and a thread throughout the rotation of the winding material wraps it at regular intervals by means of a spindle guide. In the known device, the needles are at their free end by a funnel-shaped Counterholder pulled together towards the middle. The forward and backward movement of the funnel-shaped counter holder a specially trained tailstock is necessary. Also be the needles surrounding the winding material are also guided in a spiral groove system, for which purpose as well a special drive is necessary to move the looper needles with their free ends in such a way that that these can get into the funnel-shaped counter holder.

According to the present invention, these disadvantages are eliminated by the fact that the strongly conical free-standing hook needles of the winding machine for pressing onto the goods of several opposing, spring-loaded joint parallelograms articulated on the common axis of rotation are carried and can therefore be moved in parallel. As a result of this special training the hook needles are moved both in the axial and in the radial direction, whereby the winding material is held, stretched and compressed at equal intervals along its entire length. A special counter holder is not required, so that a quick and easy introduction of the goods as well as a simple and functional design of the winding machine is guaranteed.

The invention is shown in the drawing in an exemplary embodiment in a front view:

Wrapping machine for stretching and wrapping
of ham or the like.

Applicant:

Heinz Juhrs,

Burgstädter Str. 30

Named as inventor:

Heinz Juhrs,

Hartmannsdorf (district Karl-Marx-Stadt)

The winding machine consists of the machine base plate 1, the bearing block 2, the stationary one Axis 3, the sleeve 4 with parallelogram parts 5 and hook needles 6 and the lead screw 7 for the

ao thread transport and the drive connection 8. The winding material 9 is gripped like pliers by the hook needles 6 attached to the parallelogram and rotates together with the sleeve 4 on the axis 3 fixed in the bearing block 2. The hook needles 6 are under tension of the springs 10 and are by a Hand lever 11 is actuated on a sleeve 12, which is displaceable on the sleeve 4, in connection with the push rods 13. A counter disk 14 prevents the sleeve 4 adf from sliding off the axis 3. A wheel 15 fastened on the lead screw 7 transmits the rotational movement in a certain ratio by means of gears or a chain to the wheel 16 fixed on the sleeve 4. The thread guide 17 is slidable on the Lead screw 7 mounted and secured against rotation. A releasable connection to the lead screw 7 is established by means of a hand lever 18 under spring pressure and a guide pin 19 which is movably connected to the thread guide 17. The thread tension can be changed by a thread brake 20. The handling of the winding machine is as follows: After the winding material 9 is clamped between the hook needles 6, which is done by operating the hand lever 11 , the string 21 is wound around the winding material 9 and the gripping needles 6 and tightened. The thread can be braked by the thread tensioner 20 according to the durability. The thread guide 17 is brought into the corresponding starting position by releasing the hand lever 18 and is re-engaged in a thread of the lead screw 7 by means of the guide pin 19. Then the lead screw 7

mechanically, electrically or set in rotation by a hand crank 22 and * the drive by means of the Wheel 15, the drive connection 8 and the wheel 16 on the sleeve 4 and thus on the parallelogram transferred with the hook needles in an optionally switchable ratio. Through the simultaneous rotation of the lead screw 7 and the sleeve 4 moves the thread guide 17 in a certain Ratio to the right and ties the thread 21 helically around the winding material 9. After the winding length has been reached, the thread 21 is cut off at the thread guide 17 and the winding material 9 is pulled out of the hook needles 6.

Claims (1)

Claim: Wrapping machine for stretching and wrapping ham as well as meat and sausage products a number of which are tapered towards their free end and are radially adjustable in relation to one another Hook needles hold the winding material firmly along its entire length and hold a thread during the rotation of the winding material this means a »spindle guide at regular intervals wrapped around, characterized in that the strongly conical free-standing Looper needles for pressing against the good of several opposing to the common axis of rotation articulated, spring-loaded joint parallelograms carried and thereby can be moved in parallel.
