A tack side lasting machine has two combined wiper and tack insertion devices (25; 36; 43, 45; 73, 75/5 to 8) which operate progressively along opposite side portions of the shoe. Each such device includes a friction element (25; 36; 43; 73) which first engages the shoe in the "high wood" region (26) of the upper (2) and is then moved in a direction towards the lasting margin (3) and over the insole edge. The friction element may be in the form of a strap member (25; 43), a friction roller (36) or a runner-like rigid drafting element (73). A top line presser member (35; 70) may be associated with the friction element for clamping the top line region (28) of the upper (2) against its last (1).

Acting on a column means (3) carrying a shoe (4) being worked is a fluid-operated actuator (19) longitudinally moving the shoe (4) in synchronism with two nailing hammers (37) acting on the opposite shoe flanks. Each hammer (37) is carried by an end plate (39) oscillatably mounted to a movable block (36) along a guide structure (33) for pushing the hammer (37) towards the shoe (4). The lower hammer end (37a) is elastically urged towards the edge of the shoe vamp (5) in order to stretch it when the hammer moves towards the shoe inside before the nail is driven in. The guide structure (33) is capable of oscillation about its own longitudinal axis and acts on the shoe insole (6) in order to transmit to the hammers (37) the variations in height and inclination encountered along the longitudinal shoe.

Die Erfindung bezieht sich auf eine Schuhzwickmaschine, mit welcher Tackse (4) in vorgebbarem Abstand (T) in einen auf eine Brandsohle (6) umgelegten Zwickrand (8) eines auf einen von einem Leistenträger aufgenommenen Leisten (10) gezogenen Schuhschaftes (12) eingeschlagen werden, mit einer Tacks-Ab­teileinrichtung (14), einer Tacks-Transporteinrichtung (16) und einer Tacks-Eintreibeinrichtung (18). Zur Erzielung eines konstanten Tacksabstandes unabhängig von der Relativgeschwin­digkeit zwischen Tacks-Eintreibeinrichtung (18) und Zwickrand (8) ist im wesentlichen vorgesehen, daß eine Meß- und Impuls­gebereinrichtung (20) in Abhängigkeit des in Zwickrandlängs­richtung zurückgelegten Vorschubweges der Relativbewegung zwischen Tacks-Eintreibeinrichtung (18) und Zwickrund (8) Impulse zur Steuerung der Tacks-Eintreibeinrichtung (18) aus­gibt

Side and heel seat lasting machine has two side lasting assemblies (30;30ʹ) each having a fastener-inserting tool (64) and a wiper arrangement (76;176). For providing an updraft at a pre-set location, two abutments (112) are provided, one associated with each side lasting assembly and co-operating with counter-abutments (66a;178a) provided by the side lasting assemblies, the arrangment being such that as the side lasting assemblies are moved to their operative position over the shoe bottom, the upper margin is trapped against the abutments (112) and thus, with a slipping grip, is drawn over the insole edge. The abutments are then retracted to an out-of-the-way position. The abutments (112) may be positioned either at the heel breast line region, where each co-operates with a counter-abutment (66a) provided on the tool (64) or in the waist region, where the counter-abutment (178a) is provided on a finger (178) which is arranged adjacent the wiper arrangement (176) and effects a preliminary over-folding of the upper lasting margin.

Eine Maschine zum Einschlagen von Tacksen im Fersenund Seitenbereich eines Schuhs besitzt eine Fersen-Tackseinschlagvorrichtung (6), die die Tackse des Fersenbereichs gemeinsam einschlägt, und eine Seiten-Tackseinschlagvorrichtung (7), die zusammen mit einer Zwick-Einschlag-Spannvorrichtung in Schuhlängsrichtung auf einer dem Verlauf des Gelenks folgenden Arbeitsbahn bewegbar ist. Jede Seiten-Tackseinschlagvorrichtung (7) weist ein Mundstück mit mehr als einer, aber nicht mehr als vier Tacksführungen für das gleichzeitige Einschlagen einer entsprechenden Zahl von Tacksen (5) auf. Hierdurch wird die Arbeitsgeschwindigkeit beim Seitenzwicken vervielfacht.

Außerdem kann jede Seiten-Tackseinschlagvorrichtung (7) ihre Arbeitsbahn am ballenseitigen Ende des Gelenks (B) beginnen, bevor die Fersen-Tackseinschlagvorrichtung (6) den Fersenbereich (A) freigegeben hat.

The machine is intended to operate using tacks or like fasteners and comprises individual tackers (300) mounted for movement with the wiper plates (174') of the machine which serve to position the tackers in relation to the shoe bottom. The tackers (300) are actuated progressively, starting at the so-called "back tacks" (i.e. the tacks inserted in the backseam region of the heel seat of the shoe) and progressively therefrom in pairs, one at each side of a longitudinal centre line of a wiper assembly (172'). Electronic control means are provided for controlling the sequence of operation of the tackers (300) and in addition said control means can be used to de-actuate selected tackers, according to the number of tacks desired for insertion. The wiper assembly (172') is positioned in relation to the shoe, and thus determines the "back tack" position, by engagement of a V-block (330) associated with the wiper assembly with a rearward face of the heel band (152), while the tack pattern is determined by the amount of radial movement of the wiper plates (174'), which can take place independently of any forward movement thereof. The electronic control of the machine is effected in accordance with a programmed instruction selected according to the style and/or size of the shoe to be operated upon.
