Fl~ld o~ th~ Inv~nt~Qn
The present invention re~er~ to a prophylactic having
a knitted fabric adhered to it from it~ clo6ed end. The
fabric is de~ormed in a lonsitudinal ~ensc in relation to
5 its axi~. This makes the condom highly resistant and
reli~ble, fP~tl~rin~ great practical advantage~. The
~n--~A~tUring procedure for the prophylactic of the present
invention is ~180 ~ ;1P~ be~ow.
Ba~ç~rQuud of the :~:nv~ntion
Condoms made out of latex or other in-kind elastomeric
material are known in the market, ali of which have heen
notoriou~ly and definitely irnproved by the subject matter
of the pres~nt inve~tion. It consists of the i~troduction,
during the condom ' ~ manuf ~cturing stage, of a layer of
15 knitted ~ab~ic, deformed in a longitudinal sen~e in
relation to the condom'~ ~xis, ~7hich iB preferably capab~e
o~ avoiding lon~itudinal st~etching and permitting
tLall~v~:L~al elasticity, thus decreasing almost to ~ero the
chance~ of tearin~.

complex means must be dealt with to obtain the best results
in the procedure ~or the present invention of the improved
product referred to above. It is ~c~ ry to develop the
followi~g ~oc6du. ~ t~; 1 ed below, consisting basically
5 in the manufact--rln~ of a machine that bear~ a rectangular
structure at which vertexes, by means of axles and
rin~s, pinions revolve and in turn move a flapped chai~
that carries supports, at which end~ there are hubs within
~hich axles slide. The axles have the condom matrixes
10 attached to one of their ends and at the other end they
bear sliding devices which act on cams. It should be
i7ed that the knitted fabric in the shape of a tube
i8 i~troduced into a cone, where two parallel conveyor
~ands having fa~tQning devices adhere to the fabric. o~ce
lS the fabric is cut t~rough the middle of both conveyor bands
it i8 guided and placed over the condom matrixes. The
axles where th~ condom matrixe~ :~re attached to slide
do~nwards, introducing themselves into the elastomeric
rings whic~ are located in compar~ment~ fixed to a chain,
20 which is parallel, and cooperates with the previously
r ~ ed flapped chain. The elastomeric rings fix the
fabric tight to the prophylactic. The fabric is cut at a
line above the elastomeric ring to allow the condom matrix,
upon ~liding upwards, to take along the whole set including
25 the prophylactic, the de~ormed fastened ~abric, and the
elastomeric ring, and thus free it~el~ from the ring
carrier chain. The set i5 then dipped into an adhesive
coating ~nd later placed in an oven for drying. The left

elastomeric ~ing withdrawn. The prophylac~ic is then
withdrawn ~rom the co~dom matrix to be te~ted as usual,
rolled ap, ~;11co~ d and pa ~ed.
