challenges.

There are composite reinforcements, which differ from grids, "for example with the trade name BAUSTA, Kaiser "respectively Varese, and derive either by their union with strips of an electrically welded Net or with iron arranged and fastened transversely to them are known.

It is also known, the grid with longitudinal iron, which to modify the moments of inertia of the grid under their Adaptation to the properties required due to the load serve to reinforce.

It is also known, composite grids, in which the side reinforcement iron, either in the Arranged longitudinally or in the transverse direction, are provided as a substitute for the compilation To manufacture grids and electrically welded mesh, as in the case of reinforcements with the trade names ARDING and KOMO.

It is also known to provide such composite grids with additional longitudinal bars of the desired length Achievement of appropriate sections that withstand the intended effective loads manufacture.

However, the known devices for the production of such composite reinforcements are procedural or not technologically for the realization of composite grids of the specified type suitable and cannot be modified in order to achieve this rationally.

809851/0878

The addition of lateral and longitudinal elements as well as the addition of elements of the desired Length requires a planning and implementation philosophy, which cannot be attributed to the known devices.

In addition, there would be a desire to incorporate additional elements into such "known devices" procedurally or technologically for the production of the specified composite grids enable the complete change of both the appearance and the basic idea (philosophy) and structure mean of such devices, so that in any case a different concept of construction would be used.

Moreover, in the case of the devices it would be of the known type Kind in any case, except for all changes in the structure and in the base and lateral feed elements To use actuating or adjusting elements to carry out all necessary operations.

This requirement solely as a result of a mandatory (necessary) arrangement is such that of such Device is not advisable.

This namely requires the availability of almost twice the space.

This compulsion with the associated effort is an insurmountable obstacle to penetration With regard to the finished product.

The simultaneously submitted (and therefore not pre-published) Patent application (file number:) by the applicant with the title "Device for the production of

In detail, the drive cylinder 34 pushes the Counter template "or counter-form 133 on the template or form 33" whereby the relevant Iron or wire piece 111 is clamped. So the iron or wire piece 111 takes the Shape 211 shown in dash-dotted lines in FIG.

The arms 135 are moved from the drive cylinder 41 to the support structure 40 and then from the drive cylinder 39 closed on the template or form 33. Thus, arms 135 move from position 235 in the position 335 'in which their ends 37 the respective Iron or the respective wire 111 against the template or form 331, namely specifically press against their angle 38. The iron respectively the wire 111, which or which from the template or form 33 "of the one Side and pressed from the counter template or counter form 133 and the arms 135 from the other side takes the form of a bracket 12, the long feet of which act as crossbars 69 for the reinforcement 62.

Then the arms 135 from the drive cylinder 39 spread and pushed forward by the drive cylinder 41.

Then the counter-template or counter-form is made 133 lifted up, whereby the formed bracket 12 is released. This is then made up of the group of bracing elements 14 removed by means of the ejection elements 42.

The ejection elements 42 push the bracket 12 onto the straight guides 43, 143, from which they are used to insert the bracket.
