Definitions
- the present invention relates to an electronically controlled warp selection apparatus which integrates the concept of dobby and Jacquard shedding and enables individual selection of warp yarns.
- Jacquard mechanisms mechanical and electronic, require harness cords to lift the healds which need replacing periodically.
- the oblique angle of the harness cords and the stability of the harness also restrict the speed of the weaving operation and the harness needs replacing periodically.

- French Patent 1554517 is similar to French Patent 1380967. It claims a device suitable to improve the wear on the holding member and the stop of the heald.
- EP 0544527 describes a method of moving the healds and controlling such movement which is based on a conventional arrangement of the healds as shown in its Fig. 7(A) - 7(C) and its basic claim (Claim 1). Basically a piezo-electric element is claimed.
- applicants provide a shedding apparatus that has no harness cords but is still capable of selecting individual warp yarns in manner similar to a Jacquard mechanism.
- the proposed apparatus consists of healds with warp yarns passing through their eyes.
- the healds are not connect to a frame or to a cord but can engage either in their top section or their bottom section to a reciprocally moving bar that pulls them up or down respectively.
- the engaging mechanism consists of a stationary electromagnetic or similar device that induces a linkage between the heald end and the frame section.
- One way of doing so is by pushing or pulling a swivel arm on the moving bar to clip and engage with the heald.

Description
- The present invention relates to an electronically controlled warp selection apparatus which integrates the concept of dobby and Jacquard shedding and enables individual selection of warp yarns.
- Jacquard mechanisms, mechanical and electronic, require harness cords to lift the healds which need replacing periodically. The oblique angle of the harness cords and the stability of the harness also restrict the speed of the weaving operation and the harness needs replacing periodically.
- Large repeating patterns in the weft direction require a large number of hooks which may necessitate a multi-bloc machine with an intricate harness cord arrangement.
- Dobby mechanisms do not require harness cords but they are limited in fabric design ability and may require a complicated article change procedure when another design is introduced.
- Patent No.
FR 1 380 967 discloses a warp selection mechanism of the same kind of the one set forth in the preamble ofclaim 1. - In order to eliminate the harness without losing the ability to select warp yarns individually, an integration of both concepts is proposed.
- French Patent 1.380.967 refers to "electronically controlled warp selection mechanism". In the mechanism disclosed in this patent the pulling of each heald is performed against a spring and the return movement is done by the spring. Each heald has its own driving mechanism and the actuation mechanism can work in pulling or pushing mode.
The engagement of the hooks according to this patent is very complicated. - French Patent 1048906 describes a totally different concept and mechanism of moving the healds. In this patent, each heald is engaged and is pulled at will directly by an electromagnet, to perform shedding of the warp yarns. The electromagnet must be powerful enough to pull the heald against the stress of the warp yarn. The selective mechanism is the conventional punched boards.
- French Patent 1554517 is similar to French Patent 1380967. It claims a device suitable to improve the wear on the holding member and the stop of the heald.
- EP 0544527 describes a method of moving the healds and controlling such movement which is based on a conventional arrangement of the healds as shown in its Fig. 7(A) - 7(C) and its basic claim (Claim 1).
Basically a piezo-electric element is claimed. - In accordance with the present invention, applicants provide a shedding apparatus that has no harness cords but is still capable of selecting individual warp yarns in manner similar to a Jacquard mechanism.
- According to one aspect of the present invention the proposed apparatus consists of healds with warp yarns passing through their eyes. The healds are not connect to a frame or to a cord but can engage either in their top section or their bottom section to a reciprocally moving bar that pulls them up or down respectively. The engaging mechanism consists of a stationary electromagnetic or similar device that induces a linkage between the heald end and the frame section. One way of doing so is by pushing or pulling a swivel arm on the moving bar to clip and engage with the heald. The heald is then pulled up or down and brought back by the arm to the neutral position. Once the movement cycle is completed, a pushing bar disengages the swivel arm from the heald to the other clipped position, toward the electromagnetic device. The operation of the electromagnetic or a similar device is controlled by a microprocessor in a similar manner to an electronic Jacquard. Since each heald is controlled separately, the design can extend to the full width of the fabric.
- The need to assign an electromagnetic or a similar unit to each heald imposes some restriction on the linear density of these devices. It may be preferred to stack the electromagnetic pushing devices in rows of different heights where consecutive swivel arms of different lengths, mounted on the same moving bar, pushed by electromagnetic units located in different rows. In addition, several planes of healds may be used together with their moving bars and the electromagnetic devices, in a similar manner to that used for shafts in a dobby machine. Adjacent warp yarns may then be threaded in different "shafts" of healds.
Another aspect of the present invention suggests that in the neutral position all the warp yarns would be at the top or at the bottom position of the shed and only pulling down or up operations would be performed. According to this aspect, the moving bar with the swivel arms must travel twice the distance of the moving bars of the previous aspect. - This may result in slowing the weaving operation but it simplifies the mechanism in having only one moving bar and eliminates the need for warp tension compensation during the shedding cycle.
- Yet another aspect of the present invention is to connect the bar with the electromagnetic or similar devices to the moving bar. Having the electromagnet traveling with the healds up and down by either of the above aspects simplifies the engaging mechanism of the moving bar to the healds but imposes some strain or the fast vibrating electromagnetic devices and adds weight to the moving mechanism.
-
- FIG. 1. shows a schematic side view of a heald at neutral position disengaged from both rocking hooks,
- FIG. 2 shows a schematic side view of the bottom part of a heald being engaged to the rocking hook by the pushing pin of the electromagnet unit,
- FIG. 3 shows a schematic side view of a heald being pulled down by the bottom connector bar connected to the rocking hook and forming a shed,
- FIG. 4 shows a schematic side view of a heald being pushed back to its neutral position by the connector bar and the rocking hook to its neutral position,
- FIG. 5 shows a schematic view of hooks directly connected to the electromagnets bar and moving together with it.
- The present invention is illustrated as embodied on a conventional weaving machine having an electronically controlled warp selection apparatus which enables each of the warp yarns to be controlled. Unlike Jacquard mechanisms, this invention does not necessitate harness cords and all the operations of shedding at performed by positive movements. It is possible to achieve the individual selection of the warp yarns by ascribing an electro-magnetic or a similar unit to each heald The electro-magnet is actuated by a processor that determines the shedding patter hence the design of the fabric.
According to one technique of the present invention there are stationary bars with electro-magnets or similar devices mounted on them in a row. Opposite to each electro-magnet there is a hook that can rock on a fulcrum. Each heald has at each end an electro-magnet and a hook. When the hook is rocking it engages or disengages with the heald end. Each hook moves up and down reciprocally at a frequency equal to the weft insertion rate. The electro-magnet activates the hook and induces its engagement to the heald end. If the hook engages with the top of the heald, the heald is lifted. If it is the bottom of the heald, it pulls it down. Then the hook returns the heald back to its neutral position.
This technique is illustrated in FIGS 1 to 4. - Referring to FIG. 1, there is shown the
warp yarn 1 in a neutral position and clearingbars 10 pushing the latched rockinghooks heald 2. - In FIG. 2 the stationary
electromagnetic unit 5b, mounted on an electro-magnetic mounting bar, 4b adjacent to the bottom end 2' of the heald, is actuated by the processor (not shown) to eject the pushingpin 6b which in turn pushes thebottom rocking hook 7b around itsfulcrum 8 from its latched disengaged position to the other latched position where it is engaged with theheald 2. - In FIG. 3 the top connector bar (not shown moves up and the
bottom connector bar 9b pulls thebottom rocking hook 7b and the engaged heald down forming a shed. At this point, the weft arm (not shown) is inserted above the warp yarn. - In FIG. 4 both
connector bars bottom connector bar 9b pushes back thebottom rocking hook 7b together with the heald. FIG. 1 illustrates also the completion of the cycle when theclearing bar 10 pushes thebottom rocking hook 7b from its engaged position with theheald 2. - The lifting of the warp yarn is performed in an analogous method when the top
electromagnetic unit 5a is actuated, ejecting the top pushing pin (not shown).
At the end of the cycle, when the heald is in its neutral position, a clearing bar disengages all the hooks from the healds. - The number of healds per linear length in one frame of rocking hooks and connector bars is limited by the size required for the electromagnetic unit. This number can be increased if adjacent rocking hooks have different lengths which must correspond to the position of the interceptor section of the hook in the heal Adjacent electromagnets would then be situated at different heights and will then have more space.
Another technique that may allow for higher warp density is to arrange the sets healds with their rocking hooks, the connector bars and the electromagnetic unit in planes, in a similar pattern to shafts on a conventional dobby machine.
According to another aspect of the present invention, the neutral position of the warp yarns is arranged in a plane forming an obtuse angle with the plane of the fabric. - Such configuration results in a movement of the healds in one direction only; up and back or down and back which utilizes only one set of electro-magnets and hooks located next to the top or the bottom end of the healds respectively.
- Yet, another aspect of the present invention refers to a mechanism which consists of a spring loaded hook with its connector bar linked to the bar of the electro-magnetic units and moves together with it. Such a technique is illustrated schematically in FIG. 5. where the bottom end of the heald is engaged to the hook and moves down with it and with the electro-magnetic unit. This apparatus simplifies the engagement mechanism of the hook to the heald. It necessitates a fast reciprocating movement of the electromagnets.
