`
`with regard to the arrangement of the shoe
`blanks.
`The advantage of this manufacturing
`120
`method is that a correspondingly large
`number of identical shoe blanks can be
`produced over the entire width of a fabric.
`The arrangement of the individual shoe
`blanks enables good utilization of the fabric
`125
`with minimal waste. The shoe blanks are
`completely ready for attaching the sole, and
`only one seam is required on the toe cap.
`Shoes of any size can be produced by
`selecting
`the
`appropriate
`thread
`130
`arrangement, and patterns, identification
`marks etc. for the individual shoes can be
`printed or otherwise applied to the finished
`fabric.
`The drawing shows an embodiment
`135
`example of the object of the invention, in
`which the individual shoe blanks are
`arranged in a particularly practical manner
`on a continuous web of fabric.
`Fig. 1 shows a schematic cross-section
`140
`through the fabric web shown in
`Fig. 2 in a view from above, on which
`the position of the individual shoe blanks is
`indicated.
`Fig. 3 shows part of the cross-section
`145
`according to Fig. 1 with an example of the
`formation of the individual contiguous and
`interwoven fabric strips.
`Fig. 4 shows a finished shoe.
`The fabric web 1 is a continuous fabric,
`150
`but consists of differently bonded and
`equipped strips I, II, and III. These strips
`are conveniently arranged in such a way
`that a continuous shoe upper part can be cut
`from them, i.e., consisting of one piece, in
`155
`which the strips I, II, and III then lie at the
`points where, according to their various
`designs, the desired properties can appear
`on the finished shoe.
`In the embodiment example shown, the
`160
`arrangement is such that the shoe upper
`parts 2, 3, 4, and 5 with their cap part are
`positioned next to each other in such a way
`that the fabric web 1 is utilized as
`efficiently as possible.
`165
`Here, the fabric strip I is designed as a
`hollow fabric, as it is used to produce the
`rear cap. In order to stiffen the rear cap,
`
`stiffening material can be inserted or woven
`into the cavity 6 between the upper and
`lower fabric layers 7 and 8.
`The fabric strip I merges into strip II,
`which in the embodiment example shown
`is intended to form the blade and the side
`parts of the shoe. Accordingly, the fabric of
`strip II is elastic and multi-layered. The
`fabric strip II merges into the fabric strip
`III, which in this case is designed to form
`the front cap. In the embodiment example
`shown, the shoe upper parts 2, 3, 4, and 5
`are placed together with their toe part in
`such a way that the entire width of strip III
`can be used to produce the toe caps.
`Strip III then merges back into strip II,
`which is followed by fabric strip I without
`interruption and with the corresponding
`formation.
`In this way, two strips I, two strips II,
`and one strip III form a fabric repeat A.
`Half a repeat = 1/2 A (Fig. 3) is therefore
`required to make a shoe. As many repeats
`A can be produced side by side at the same
`time as the width of the loom used permits.
`The individual fabric layers of a multi-
`layer fabric can be joined in any way:
`however, as can be seen in Fig. 3, this is
`usually done during the weaving process
`itself.
`In this fabric, layer 7 represents the
`perfectly even and smooth surface of the
`fabric 1 or the finished shoe. To stiffen the
`fabric strip III or the layer 8 of the fabric
`strip I, stiffening threads 9 are inserted into
`the fabric, which should be sufficient for
`stiffening the rear cap in most cases, for
`example. These stiffening threads are either
`made of hard material, such as the so-called
`Sirius
`threads. They
`can
`also be
`impregnated
`with
`cellulose
`and
`subsequently hardened. If stiffening of this
`strip is required, stiffening threads can also
`be inserted into strip II.
`If the stiffening threads consist of
`subsequently hardenable materials, these
`can be introduced into the fabric in such
`large numbers that during hardening, which
`can be carried out both in the fabric and in
`the finished shoe, the textile threads lying
`next to the stiffening threads are also

`
`impregnated and thus also stiffened, so that
`a dense, continuous layer of fabric is
`created. Only certain threads of the shoe
`fabric can be made of hard yarn, for
`example, or can be subsequently hardened.
`205
`In this way, all parts of the shoe can be
`produced with the desired stiffness.
`The shoe soles 10 (Fig. 4) are attached
`according to the known methods, and
`lacing holes 11, eyelets etc. are also
`210
`attached to the shoes in the known manner.
`In the embodiment example shown, the
`individual shoe upper parts are sewn
`together at the toe cap.
`The distribution of the individual blanks
`215
`2 through 5 on the fabric web 1 depends on
`the size of the shoes to be produced, which
`is already taken into account during the
`construction of the fabric. Accordingly, the
`pattern imprint for the shoes can be made in
`220
`the entire piece, just as it is also possible to
`provide corresponding cap or side parts
`with punched decorative openings at the
`same time as punching.
`In addition to sports shoes, other items
`225
`of footwear, such as sandals, gaiters,
`overshoes, etc., in which certain areas are
`to be stiffened, can also be produced in the
`manner described. Fig. 4 shows
`the
`arrangement of fabric strips I, II, and III.
