Embodiment Construction

[0026] Referring to the drawings, reference numeral 1 designates a machine for manufacturing a web W of composite material according to the invention.

[0027] The material web W has a main direction of extension D and comprises a first material web W1, elastic threads T and a second material web W2, the elastic threads T being positioned transversely to the direction D according to a predetermined arrangement or pattern (eg a zigzag configuration) and glued to the The material web W1, the second material web W2 is attached to the first material web W1 and to the thread T.

[0028] Practically and preferably, the material web W is an elastic strip, which is preferably stretchable in its main direction of extension D.

[0029] The machine 1 comprises advancing means by which the first material web W1 is advanced in the feeding direction D1 and along the feeding path P1.

[0030] The machine 1 comprises means for feeding the elastic thread T in a feeding direction D2 and along ...

Abstract

A machine (1) for making a composite web (W) comprises a drum (21) for supporting a first web (W1) along a feed direction (D1), a station (2) for picking up an elastic thread (T) to be associated with the first web (W1) and a system for feeding the elastic thread (T); the machine (1) comprises a system for arranging the elastic thread (T) according to a predetermined pattern and a station (3) for applying the elastic thread (T) to the first web (W1) according to that pattern; the thread arranging system comprises first hooks (6, 13) and second hooks (7, 15) positioned on opposite sides of the feed direction (D2) of the elastic thread (T) and movable between a close-together position and a spaced-apart position along a direction (D3) transversal to the feed direction (D2) so as to engage the elastic thread (T) alternately and in sequence in such a way as to define the above mentioned pattern during feed from the pickup station (2) to the application station (3); the drum (21) for supporting the web (W1) on which the elastic thread (T) is released defines a system for unhooking the elastic thread (T) from the first hooks (6, 13) and from the second hooks (7, 15).

Description

technical field [0001] The invention relates to a machine for producing a web of composite material, in particular a machine for producing a web of elastic material comprising at least one substrate and elastic threads applied to the substrate. Background technique [0002] A known type of machine for applying elastic threads to a substrate, in particular in the form of a material web, is described in document EP0955978B1. [0003] The machine lays elastic strands transversely on a web of material and includes a pair of wheels inclined towards each other, each wheel being provided with strand holding fingers on its respective outer cylindrical surface, which engage the strands unwound from the spool. elastic cord. [0004] The axes of rotation of the wheels are transverse to each other, the wheels are close together where the line is picked up by the respective fingers, and farther apart where the line is applied to the material web 1 advancing in the production line.
