B02 - Upper preparation and stitching machinery

Machinery, equipment and accessories for upper parts manufacture and their joining by sewing (the top of the shoe).

Machines that equalize the thickness of the shoe upper leathers removing material from the flesh side. It can operate edge skiving by means of templates, to be made following a defined geometry. Average working width between 400 and 600 mm.

Machine used to stamp the identification of shoe upper parts. Several versions are available, starting from mechanical to computerized and from hand-operated to automatic and digital control types.

Machine which reduces the thickness of the leather on the parts that constitute the shoe upper in accordance to the requirements of the shoe model. The bevel or "bevelling" edge is made by cup-shaped knives that rotate at high speed and with preset inclination. The operation can be hand-operating or by templates. Traditional or computerized versions are available.

Machine configuration with rotary plate, book-closure plates hinged or pressure roller for hot assembling of reinforcements of various types and material to the upper. Versions from manual to mechanized.

Several configurations available, of this type of machine that applies self-adhesive reinforcement tapes on the edge of shoe uppers or on portions of shoe uppers. They can perform different additional operations such as stitching flattening, edge milling and automatic cutting tape.

Crimping and shaping machine suitable for single-piece bootlegs. It is equipped with two vertical plates within which moves the arm that drags the upper forcing it to slither between the plates.

Machine equipped with work table and striking plate with matrix on which is printed the design to be realized. Performs effects of plating, embossing and also drilling and shearing. Versions from manual to automated.

Machines that produce high frequency energy that heats and softens the cover of the shoe upper performing particular relieves by pressure on the mold. Versions from simple single-user to the linear continuous production.

Machine that realizes a series of aligned holes along the edges or in array in the middle of the parts that make up the shoe upper. Machine equipped with a single punch needle and continuously fed. A peculiar type of punch is that used to make holes for the crossing of the laces, that drills simultaneously the shoe upper on both sides.

Machine that folds the edge -already skived- parts of the shoe upper, using thermoplastic adhesive and operating cutting measures along concave and convex curves. Versions level from simple to complex in the computer control of process parameters.

Machines in versions from simple irons, to flat or roller presses for applying cold/hot reinforcements on the shoe upper.

Machines and equipment for gluing on reinforcements and parts of shoe uppers and lining. Spray and roller versions.

Machine running straight or curved pleats to create patterns of decoration of uppers for footwear, parts and components.

Sewing unit including supporting surface for the material. The unit can perform several stitch types (knotted, single or double chain stitch, overcast, zig-zag), different types of sewing (one needle, two needles, straight, zig-zag) and with different transport systems (feed dogs, feed dog and needle, needle and feed dog-legs, others).

Stitching unit with arm type counter top for the material. The unit can perform several stitch types (knotted, single or double chain stitch, overcast, zig-zag), different types of sewing (one needle, two needles, straight, zig-zag) and with different transport systems (feed dogs, feed dog and needle, needle and feed dog-legs, others).

Stitching system with support for the material column type. May run several different stitch type (knotted, single or double chain, overcast, zig-zag), different type of sewing (one needle, two needles, straight, zigzag) and different material feed system (simple with a feed dog mechanism; feed dog and needle feed; feed dog plus needle feed plus alternating presser feet; upper differential; others).

Sewing unit equipped with special stitching heads and templates. In the versions with overcast lockstitch and curved needle can carry out various types of seams.

Machine equipped with a long anvil support with a working plate, particularly suitable to beat and iron upper and boot seams.

The machine presses the seam by two pressing rollers and simultaneously applies a reinforcement tape of various widths on the seam.

Machine equipped with a knife blade which oscillates and counterblade feeding device, suitable for trimming the linings of the uppers. Available in different versions depending on production needs.

Solid frame structure machine for chain stitching joining the lower edge of the upper with insole ("slip-lasting" method).

Machine with pressure matrix for the application of eyelets, rivets, nailheads, hooks, rings, vis. Ranges from fully manual handling up to the automatic feeder of small parts system and automatic material feeder to measured steps.

Numerical control machines that realize ornamental drawings by vectorial files. They are equipped with one or more application heads, in order to apply various metal decorations like nailheads, eyelets, rivets. The leather is fixed on templates specially prepared; completely automated.

The laser systems for the leather use a CO2 source; the power can be normally between 50 and 500 Watt. They are usually equipped with special software able to use vector files, and check the many processing parameters: power, speed, frequency. The laser systems are mainly of 2 types: plotter and galvanometric. In the second one the laser beam is controlled by special mirrors, moved with great speed and accuracy the highest quality results and is used for engraving, perforation, raster photo effect, cutting.

Pressing machine equipped with suitable shaped mould in hot station and, if present, cold station. It can give a bend on the front part of the flat upper such as to make it adhere easily to the last model.

Machine where the uppers with eyelets are laced up to a predetermined distance. Knots and thread trimming are done automatically.

Pneumatic machine that overturn the uppers of boots. Configurable for every leg height of boot.

Caro cliente e caro fornitore,

In questi giorni stiamo vivendo una situazione imprevedibile, complessa e con la quale non avremmo mai voluto confrontarci. Le imprese associate ASSOMAC, sia strutturate che di piccole dimensioni, sono messe a dura prova e si trovano obbligate a decisioni difficili in un contesto internazionale in continuo cambiamento.

In tutte le nostre aziende, dopo le disposizioni governative per una cessazione delle attività, è sempre più crescente la preoccupazione per la capacità di “resistenza dell’impresa” anche legate alle dotazioni finanziarie per rispettare le future scadenze di pagamento nella salvaguardia dei nostri collaboratori, fornitori e clienti. 

Riprendendo quanto scrive il presidente di Confindustria Vincenzo Boccia nella lettera ai presidenti delle Associazioni Confederate del 31 marzo scorso:

La tenuta del sistema economico e delle filiere dipende però anche da noi, dalla nostra etica della responsabilità e dai nostri comportamenti, per questo faccio un appello a tutte le nostre imprese e lo faccio riportando una frase di Stefano Scaglia, il nostro Presidente di Confindustria Bergamo, un territorio tra i più colpiti in questo momento, che ha dichiarato ieri: “Ogni impresa, indipendentemente dalla sua dimensione, categoria o settore merceologico, è funzionale alla sopravvivenza del nostro tessuto produttivo. Mantenere gli impegni presi nei pagamenti, salvo gravi e comprovate difficoltà, è la decisione che garantisce continuità a tutto il nostro sistema. Adesso è il momento della responsabilità sociale, possiamo e vogliamo essere il centro e i promotori della nuova rinascita”.

In questo momento le nostre imprese stanno cercando di fare il possibile per ottemperare a tutti gli impegni di pagamento nei confronti dei propri fornitori proprio per non incrinare rapporti commerciali storici e non alimentare un dannoso effetto domino.  

Fiduciosi che la collaborazione etica del mondo imprenditoriale unitamente al rispetto degli impegni presi consentirà una pronta ripartenza della filiera pelle e dell’intero sistema produttivo italiano.

Un caro saluto.

Presidente Assomac
Gabriella Marchioni Bocca
