Description

2598 1 59

The present invention relates to a machine for obtaining in a single pass and continuously a hot-set fancy yarn allowing, unlike known methods, to obtain particular effects of elasticity and volume of the fancy yarn by adjusting the voltage to the power supply units of the

individual wires components.

The presently known methods further require the performance of the various operations on separate machines with a substantial increase in the cost of installation, the time required to complete the job completely and with an increase in manpower. The machine in question is characterized by: a) means for feeding various individual yarns, at least one of which preferably central forming the core of the yarn and the other (s) being effect yarns, through elements of feeding with the assistance of preferably electronic members which, according to a variable program, control the feeding speed to obtain interposed or superimposed color effects along the wire or core wires; b) a suitable joining member to promote mutual binding and effect among said yarns; c) a coil or equivalent means carried by a pin pierced axially, in the axial bore of which pass the core thread (s) and the effect thread (s) while the binding thread serving to connect the core thread (s) the core threads to the effect thread or threads unwinds from the spool; d) a false twist device at the outlet of said spindle and integral with it to establish a false twist between the core thread or threads and the effect thread or threads passing through the axial bore of the core. pin carrying the wire with the wire which establishes the connection, preventing its slackening when the false twist decreases downstream of the false twist device; e) an additional feed device at the output of the false torsion device; f) at least one oven for fixing by heat the fancy yarn thus obtained; g) an additional device for pulling down from the fixing furnace, the speed of which is adjustable in conjunction with that of the feed device at the outlet of the false twist device to adjust the feed speed of the fancy yarn in said oven; h) a sizing device; i) a final receiving spool of the

fantasy finished.

The accompanying drawing schematically shows a preferred, non-limiting embodiment of the machine in question. Figure 1 shows the arrangement of the various elements to simultaneously establish two fancy yarns

hot set in a single hot set furnace.

FIG. 2 represents, again schematically,

a detail.

The machine in question provides a fixed fancy yarn in a single pass and comprises: a frame of the twist type as in Fig. 1 carrying a positive feed member (1) (i.e. wherein the wire speed is equal to the peripheral speed of the feeder rollers) for the wire referred to as "core wire"; two positive feed elements (2 and 3 ') symmetrically with respect to the core yarn (A) for feeding effect yarns (B, C); a device (3) for

promoting the bond and effect between said yarns; a spool (4) carried by a pierced spindle (5) where the wire (6) constitutes the binding of the "effect", a false twist device (7) integral with the spindle which generates the false twist on the various son (A, B, C).

This false twist established by said device (7) at the base of the spindle is the phenomenon which allows the formation of fancy effects and is the object

of the French patent Chavanoz.

Along the path of the wire, an element

feeder (positive) (8) is placed at the head of a hot setting furnace (9) while a feed element (positive) (10), a sizing device 5 (11) and finally a take-up reel (12) complete the machine.

The feed elements (2) and (2 ') are actuated by one or more electrical devices, not shown which, according to a random program, control the feed speed of the two wires (B, C) to obtain color effects introduced or superimposed along the wire or core wires (A) coming from the feed element (1). These effects are linked by the thread (6) which prevents their slackening when the false twist 15 decreases downstream of the false twist device (7) which

rotates integrally with the axially drilled spindle (5).

In the oven (9), in which the temperature can be suitably regulated, the yarn passes with a feed regulated by devices (8) and (10) and is then sized by the device (11) before being collected ( 12). Exhaust fans (13) collect the

fumes from the oven (9).

It has been provided that electronic devices or of another type can simultaneously adjust the speed of the elements (1, 2, 2 ', 8, 10, 12) to obtain any type.

effect on the fancy yarn produced.

Claims (6)

CLAIMS. 1. Machine for obtaining in a single pass and continuously a hot-set fancy yarn, characterized by a) means for supplying various single yarns 5 (A, B, C, etc ...) comprising at least one yarn ( A) preferably central constituting a core thread while the other or the other remaining threads (B, C, etc ...) form effect threads passing through supply elements (1, 2, 2 ', etc ...) with the participation of elements, preferably electronic, which according to a variable program control their feed speeds to obtain color effects interspersed or superimposed along the core thread or the threads soul (A); b) a junction element (3) suitable for promoting mutual bonding and effect among said threads, c) a coil or equivalent element (4) carried by a pin drilled axially (5) in the axial bore of which pass the core thread or the core threads (A) and the effect thread or the effect threads (B, C) while a connecting thread (6) of said thread or threads (A , B, C, etc ...) is unwound from the spool; d) a false twist device (7) at the outlet of the spindle (5) and integral with this spindle to generate a false twist between the core thread or threads (A) and the core thread or threads (A). effect (B, C) passing through the axial bore of the spindle (5) and a wire (6) which forms the bond preventing slackening when the false twist decreases downstream of the false twist device (7); e) another feed element (8) at the output of the false torsion device (7); f) at least one oven (9) for fixing by heat the fancy yarn thus obtained; g) another traction device (10) downstream of the fixing furnace (9), the speed of which is adjustable in collaboration with that of the feed device (8) at the exit of the fancy thread in said furnace (9); h) a sizing device (11); i) a final take-up reel (12) of the fantasy finished. 2.
