_ -2-1 The patent deals with reinforcements u~ed in cons-truction , such a~ ln pillars, beams, support3, girders, etc. The manufacture of reinforcements of thi~ kind i8 carried out either on site, where the construction i8 taking place~ or in a factory~ in which case the prepared reiafor-cements are transported to the construction aite to be arranged in the place in question, that i~ for assembly.
A method of csrrying out these reinforcements elther on ~ite or in a factory, by which a first cutting and aha-ping operation i8 carried out on the different piecos ofiron needed for the said reinforcement. These pieces of iron are then placed on tables or trostle bonts, where a pre-assembly of the reinforcement to be made is carried out. Next, the workers proceed to bind together thc mee-15 ting points of the pre-assembled reiuforcement in the pla- -~
ce~ in queJtlon, with the re~nforcomont being ~tatic on the trestle bents and the worker or workers mo~ing along ita ~-lenoth until all tho necos~ary points have been bound toge- ~-~
thor~ thuo giving shape to the reinforcoment.
For binding together the mootiDg points~ the tradi- ~ ~
tional way i8 known~ ba~od on manually placing a wire at `
each point ~nd later braiding it by moan~ of 8 tool~ for in tanco a psir of plior~ or p~ncera.
Thia traditional ay~to~ naeda apecially akilled workors, callod ~teel erectora or atoolworkora~ who uaually do~olop a high level of production~ in tho region of 45 to 50 Kg. of iron por hour and even up to 60 Kg. of iron per hour por poraon. ~ e problem with this traditional mothod of asaembly lies in the high production costs, due especia 3 lly to the high coat of akilled labour aod its ~carcity aa ~ '''~

.4 More recently, pre-shaped clips are being used which are fitted where the reinforcement members croas. These clip8 are provided with projectiona which are picked up by a tool which automatically braids the said projectiona until a perfect closure of the clip ~8 obtained. ; --The advantage o using clips and automatic braiding toolJ is that highly akilled labour i8 not needed but that -~
aemi-skilled workers and even apprent~ices can be used. In thia case~ the productio~ is similar to with the previoua ~ystem, although with the inherent advantage of employment and the pos~ib~ y of finding suitable personnel.

1 xible machine which has an area for the longitudinal irons of the structure to be arran~ed and another adjacent area -~ -for the transverse irons, which are 8tacked up. In this instsllation, traction on the longitudinal irons is carried out among the stacked transverse irons, taking one transver se iron each time, which is bound in the traditional way until the structure is completed.
This installation i8 complex ~n itself and in the way of proceeding to make up the structure~ meaning that its 10 use in practice i8 not ~iable given that it is neither -~
chenper than trad~tional procosaes nor increases production. ~ -one aim of the patent is to attain a method of pro- ~ ~ `
duction which provide~ a greater output of reinforcements - ~ -of the order of at leaat 30 per cent and usually 50 per 15 cent more in equality of condltions, with which the cost of -~ -the finished reinforcement can be quite considerably chea~
ned~ even taking i~to account the amortization or ropayment for the installations and the toola.
Another aim of the patent i8 to obtain an automatic or aemi-automatic installation which mo~os the reinforcements for their pre-aaaembly and assembly~ and in which the workers remain ststic wh~le the reinforcements are moved in front of their work ~tation~.
To put the patont lnto operatlon~ pre-ahaped clipa and braiding tools are uaed~ after the clipa have firat been positioned by the worker or operator. Each worker is pro~ided with an automatic braider and a aufficient amount of clip~ to be arranged at the binding points of sach rein-forcement. me operation~ of cutting and ~haping the pie-3 ces of iron are carried out in the same way as with the ;~
` - ~5~ 2 ~ 2 2 4 ~
1 tradit~onal methods, with the ~pecial f~atures of the patent coming in after the shaping of the components.
The existence i8 claimed of a set of wagons or carts on which are situated the trestle bents or A-frames that receive the already shaped pieces of iron~ in that these wagons are fitted with suitable means of rolling along railJ
JO that they can move in at least one direction. When the different pieces of iron have been ~u~tably cut and ~haped, the pre-assembly of the reinforcement is carried out on the tre~tle bent~ on the ~aid wagons.
In this situation, each wagon is moved along tho rails of this pre-aasembly area to another rall in whioh mean~ are fitted to move the wagonC at a variable speed and in that these means go together with other ones in the lower part of each wagon. Normally in this binding lino~
a variator motor is provided, with a connection on it~
~haft outlet for an endless chain of a ~imilar length to that of tho rail; this endle~s chain will engage with the projections on the wagons and move them along the assembly track-On thiJ assembly track, the roinforcement on the wagon~ circulateo at a cer~ain ~peod whilo the worker~
remain Jtat~onary~ b~nding to~othor tho mooting points of the roinforcement with tho clips and tho braidine machino 25 as oach ~oction of the roinforcomont passes in front of ;~
their work ~tations.
The number of workors is logically variable~ given that it is obviou~ to point out that, in general terms, a greater work rate can be achieved with a higher number of 3 operators.

1 The traverse speed of the ~agons which carry the reinforcement i8 variable, as was stated previously~ and it should be considered that with an equal number of operators or workers, tl1e speed of the wagon will be slo~er when the ~ ;
5 reinforcement i~ more complex and has a ~reater number of binding points in each section.
At the end of the work track, any specific reinforce~
ment will be conpletely finished and ready to be moved into stock~ loaded onto a lorry~ etc. It must be considered hore 10 that the pieces of iron for as~embly of the reinforcement on site are placed on the wagon at the beginning of the process, so that when the reinforcement is fini~hed, these pieces of iron can be fastened to it so that they are controlled until the time of assembly on site.
When the reinforcement has been taken off the wagon, this move3 to another area with rails, adjace~t to the work -area, where the wagons can be loaded again before moving to `~
another or to the firfit assembly line.
The pos6ible combinations of work tracks and pre-assem ~ ;
20 bly areas~ as well as unloading aroa6~ are infinite and will depond~ as is logical, on variables, such a6 the space avai-lable~ the ¢apacity that the in~tallation is to be providod with~ etc.~ as will bo pointed out later in relation with tho sheots of drawiDes.
In the pre-assembly areas~ the wagons can be provided, if dosired~ with a gentle traverse movoment towards tho work track~ and the worker or workers could porfectly carry out the pre-assembly of the reinforcement during this movemont.
