Abstract

This invention is about a weaving machine which can be split from a near vertical splitting plane in form of tailstock structure and the remaining head stock of weaving machine stays stationary on the foundation. Beam change will effect by removing entire tailstock structure, which is having its own castor wheels for easy movement, with all heald frames in their near normal fitment (avoiding a "free-fall") by comprising the integral heald frame working guides, integral shedding under motion, stop motions and guide rollers to move away from weaving machine head stock. Same is to be replaced by another tailstock structure with new warp beam, preparation on which is previously done on a "stand-by" mode, that is away from the machine and without stopping the machine itself for preparatory work, which can be so quickly attached and detached in an almost plug-in and plug-off style, is a unique and novel arrangement. And above all the tail stock structure itself has the arrangement to facilitate drawing-in with new beam, frames and reed held on itself.

Description

TITLE OF INVENTION:

"WEAVING MACHINE TAILSTOCK WITH INTEGRAL HEALD FRAME GUIDES & SHEDDING UNDER MOTIONS"

The following specification particularly describes and ascertains the nature of this inventions and manner in which it is to be performed.

DESCRIPTION:

A. TECHNICAL FIELD OF THE INVENTION:

The invention relates to the field of textile engineering and more specifically to warp beam replenishment systems on weaving machines.

B. PRIOR ART:

1. Indian Patents - No prior art with even the slightest resemblance in textile and weaving machine field.

2. European Patent - EP 1696062 A2 - Method and device for replacing and/or transporting a frame module of a loom. (This isn't about a split loom, it only describes and claims a transporting device, apart from the loom itself, to transport drawn-in beam and healds for loading on to a loom as a mere "transporting system". I have still cited it here, but not discussed it in detail as their objectives claims and utility are entirely different than this invention.)

3. United States Patent - US 5322088 A - Split loom having a removable loom part including detachable harness holding apparatus (This prior art a split loom as well as a replenishment system but it has prominent disadvantages and how this invention differs from, and how those disadvantages are overcome by this invention is described in detail below)

This prior art numbered US 5322088 A above, and the references thereto did not address following issues and thus such attempts made previously, did not find any commercial success, because - a. The split arrangement was limited only to warp beam and warp stop motion and heald frames remained out of scope of quick changing in a real sense. It was more of a detachable heald frame holding apparatus than a clear cut splitting of head stock and tail stock structure from a vertical plane for quick and "plug-in" type of easy replacement. b. Further more because the plane of splitting was oblique, removal of such split structure needed bigger space at the back of the weaving machine and hence such machines could only be installed in buildings where space or machine layout is planned in advance, and such machines could not be fitted in machines of non-split design. Prior art split machines needed significantly wider beam alleys in order to accommodate bigger size of split structure as well as for the additional structure carrying them. c. The split loom cited in above prior art needed another carrying device which will lift the split loom tailstock structure and place it gently on the main body structure for installation. This means the prior art needed another external device to complete the style changing process. d. All the harnesses/drive links & locks connected to heald frames needed to be dismantled from both sides of all the heald frames, as the harnesses and entire shedding under motion remained on main loom body, in this prior Art, proves to be a significant and huge dis-advantage of such systems. e. The drive links (at least two per heald frame), which are not so easily accessible on a weaving machine, they must be dismantled in detail and re-installed while putting every new beam. This also needs a device to bring all the harness frames and their respective drive elements in a pre-determined position in order to engage, as the prior art itself describes it. Upon unlinking these drive elements, the frames get a "free-fall" and need another additional mechanism to engage and to hold them in place until they re-engage back with the weaving machine stationary body. This is a significantly time consuming job and couldn't save significant time in such instances. Thus such devices were not commercially successful till date.

As a result all of above, only the warp stop motion preparation time (drop wire putting time) was saved in such prior art arrangements and thus it did not become practical to invest in such type of conventional quick change systems available on the market just for a gain of only a small amount of time saved. C. WHAT'S NOVEL IN THIS INVENTION:

This invention aims at making a weaving machine which can be split from a near vertical splitting plane in form of tailstock structure and the remaining head stock of weaving machine stays stationary on the foundation.

Beam change will effect by removing entire tailstock structure, which is having its own castor wheels for easy movement, with all heald frames in their near normal fitment (avoiding a "free-fall") by comprising the integral heald frame working guides, integral shedding-under-motions (no drive links connecting to the frames are removed here), stop motions and guide rollers to move away from weaving machine head stock. Same is to be replaced by another tailstock structure with new warp beam, preparation on which is previously done on a "stand-by" mode, that is, away from the machine and without stopping the machine itself for preparatory work. This will require un-fastening and re- fastening only a few bolts and dis-engaging and engaging only one easily accessible quick link per heald frame which connects the under motions on this tailstock structure to the head stock, which can be so quickly attached and detached in an almost plun-in and plug-off style, is a unique and novel arrangement.

D. OBJECTIVES OF INVENTION :

1. Wherein, the main objective of the invention was to provide a near vertical split in the weaving machine for an instant beam change system so as to provide a method involving minimum or no dismantling of harnesses. In addition to other parts obviously integrated with the tailstock structure, the Heald frames along with the Drive links and dobby-under motions also and must be retained in their near normal working condition and position and as an integral part of the weaving machine tailstock structure, so this is one of the most distinctive and unique objective of this invention.

2. Wherein, the secondary objective of the invention was to intentionally retain the heald frames located in their working guides and along with the harness drive links and entire dobby under-motion integrated with the tailstock structure and achieve an optimum arrangement having very few nuts and bolts for securing it to the main body of weaving machine and to provide the instant change system in such a way that the beam drive, warp tension sensing and positive easing etc. are easily dismantled and assembled by simple and partly or fully detachable links during an event of changing the beam.

3. Wherein, another additional objective of the invention was to device it in such a way that the same tailstock structure can be used as a stand/apparatus for "drawing-in" of threads offline, that is for taking the threads through the eyelets by leveling of frames and providing a supporting device for placement of reed by means of a simple arrangement, thus bringing about multi- functionality to the apparatus.

E. BREIF DESCRIPTION OF DRAWINGS :

The invention will now be described with the help of a drawing accompanying this specification wherein salient features have been shown by suitable numerals and referred to appropriately in the following description.

Patent Illustration comprises 8 diagrams:

Description on Diagram - 1 : Arrangements on tailstock Structure-

Diagram 1 shows how overall arrangements are made on tailstock structure. Numbered 1 is a basic framework of the tailstock structure of between 400x500 mm and 1200x1500 mm in size and having length as per width of the machine, suitably made from either sub frames or by fabrication from hollow steel section of round/square/elliptical/rectangular section, hollow section contained of between 40x40 to 75x75 mm, with wall thickness between 2 and 8 mm, or the combination of these two,. Two portions extend towards the machine side and it mounts two integral guide blocks for heald frames which are numbered 2. These frame guides are adjustable and form an integral part of the tailstock Structure, and this is unique, the heald frames are kept in their working guides during the movement of tailstock Structure.

Number 3 and 4 are two brackets on each side of the tailstock Structure, at the bottom portion which are meant to provide assembly place for shedding under motions. This is another unique feature of this invention and it enables carrying entire shedding under motions, integrally, along with tailstock Structure during its movement on shop floor.

Numbered 5 is a Bracket for holding a pair of large rollers numbered 6 and 7, of size 90 to 150 mm and having wall thickness between 3 and 8 mm. Roller 6 is called bottom back rest roller or and Roller numbered 7 is called top back rest roller as they are placed in a vertical layout, as a novelty this is intended to save space needed for the tailstock structure.

In the middle of these, another relatively smaller roller, numbered 8, called as whip roller is intended to sense warp tension and is suitably preloaded by springs (or load cells). Two mounting pads are provided, one on each side, immediately above and in front of the back rollers, numbered 9 are intended for fitment of the warp stop motion which generally is in the form of long bars passing from one end to the other by suitable mountings. Numbered 10 are series of round slots made right in front of the warp stop motion mounting pads, are intended for locking of lease rods which get inserted in to the warp threads for separation of thread layers. Roller 8 sits on pair of brackets numbered 11 which are one each on both sides. Lever or connecting rod numbered 12 fits on both ends of this and is intended to connect the whip roll to positive easing and tension sensing arrangement. Further numbered 13 is a bracket on which an arrangement for holding the heald frames in level condition during transportation of tailstock structure from machine to preparatory and back, is mounted, another first attempt to bring multi-functionality to the tailstock structure as this gadget enables the tailstock structure itself to be used for drawing in of warp ends through frames.

Numbered 14 are two supporting devices which are intended to serve guiding of heald frames during weaving operation, and to prevent them from swaging sideways. Numbered 15 are two brackets, which are in pair on each side of the tailstock structure, these are intended to serve purpose of beam pipe guiding. These guided are adjustable (back and front depending on number of frames loaded on the machine) and integral with the tailstock structure. Numbered 16 on both sides are levers, which form third point for locking both ends of beam pipe Numbered 17. This lever is pivoted in frame in such a way that it can swing out to take exhausted beam and get back on locking the new one. Numbered 18 are end caps, about 100 to 200 mm in diameter, which are mounted on beam pipe on both end faces of it, with suitable fastners. Together parts 15, 16 and 18 form a firm lock for beam pipe 17 in such a way that beam can only rotate and any other movement is not possible. This forms a bracket-less open-axis beam holding arrangement which is of a unique kind never attempted before.

As one of the primary embodiments, Numbered 19, is a chain-wheel which is intended to drive the beam. Conventionally gears are used to drive the beams but they form a point contact against warp thread tension which is wound on beam and tends to turn it around its axis. Chain creates equal and opposite wind-unwind type tension (torque) on the beam pipe and this greatly minimizes the hopping of beam. This is another one of a kind though never applied in such context. Conventionally the beam keeps hopping on the machine as it is opposed on only one point or teeth of gear, but here it is locked on all teeth of the chain which has encircled itself on the chain wheel. This generates a balancing force for warp tension which is of equivalent geometrical nature. This stabilizes the overall tailstock structure operation in a great way.

Number 20 are parking slides for mounting the tailstock Structure on the machine where it mates with identical part on the head stock as shown in diagram 4. This is a plate, which is about 5 to 15 m in thickness and has two geometrical steps which, upon mating with the head stock, lifts the castor wheels supporting the whole tailstock structure off the ground and makes it stable, and bring it to a position of clamping on the machine with the help of mounting points 21 and 22 which are on both sides of the machine. These are only points which need threaded fasteners to be attended during dismounting and remounting of tailstock structure on the machine. This is intended to save time spent on beam changes, and added with other unique and novel arrangements, takes this detachable tailstock structure to another class of user friendliness, unlike its predecessors.

Numbered 23 are castor wheels of suitable capacity mounted on all four corners of tailstock structure to facilitate easy movement of the same on the shop floor. These wheels get lifted off ground, as explained above, when the tailstock structure gets stable and clamped on to the machine at points 21 and 22.

Description on Diagram 2 - PLAN (Top view) of tailstock structure

As an example this diagram and further diagrams too, illustrate a tailstock Structure for 12 bottom harnesses or heald frames configuration. There can be more harnesses depending upon machine type and shedding apparatus capacity. Some numerals from 1 to 23 are repeated in this diagram, these are same parts from earlier diagram but from a different view angle. Further numbered 24 and 25 are quick - Snap-on links which get engaged with shedding device output levers on the machine head stock. Numbered 26 and 27 are bottom harnesses themselves. Getting these harnesses to become integral part of detachable tailstock structure has been the one of the highlight achievement of this invention.

Description on Diagram 3 - tailstock Structure with shedding under motions assembled - detail view -

Refer to earlier diagrams for the repeating numerals almost all of them are repeat as only view point is changed. New additions are Number 28 which are Harness levers mounted on bracket 3 and 29 are harness levers mounted on bracket 4 with a suitable arrangement of small brackets numbered 30. All of them (28 & 29) transfer horizontal motion of the harnesses elements numbered 31 to vertical ones driving the heald frames. Numbered 32 is a plate with a slot 33 at its middle portion which enables it to slide forward and backward. Moving this plate forward provides support to all heald frames at the center position as all of them rest on this in event of tailstock structure movement. As an alternative embodiment of this invention the function of plate 32 can be attained at the bottom by providing a fixed locking pins for all connecting links (24) where in the operator will unlink all connecting links one by one from the output drive levers of shedding device of the weaving machine head stock and load them on a stationary or fixed pin provided on the tail stock frame structure which are arranged in such a manner that upon loading all links on the fixed or stationary pins, all healds are leveled. This uniquely adds to multi-functionality to the tailstock Structure as it can be used as it is, for drawing in of threads as described in diagram 8. Description on Diagram 4: tailstock structure Shown in normal working condition and position

As an example this diagram shows Detachable tailstock structure in use on a typical head stock of weaving machine. Again the numerals are repeating from earlier diagrams as they resemble same parts. Further numbered 34 are three bearings which are clearly seen in this view, to be supporting the Beam. Numbered 35 is foundation block of the machine which serves to support the parking slides numbered 20 at the bottom of the Back Beam Structure. Numbered 36 is the bolt place for fastening the Back roll bracket numbered 5 to tailstock structure frame numbered 1. Numbered 37 are upward links or connectors to the heald frames which are attached on top of the harness levers. Number 38 is chain driving the beam or let off motion. Numbered 39 are working guides for two full complement selvedge formation frames numbered 41. Numbered 40 are the rest of the heald frames which are guided on the side guides numbered 7 on the Back Beam Structure.

Description on Diagram -5 - Head Stock and tailstock Structure separated

Again the numerals are repeating from earlier diagrams as they resemble same parts. Further numbered 42 is positive easing cum warp tension sensory mechanism Link 12 directly connects to this and supports Whip roll numbered 8. Number (12P) is parking place for lever 12 in event of movement of tailstock structure. Number 43 are output levers from shedding device which get connected with quick links 24 and 25. With a little backward movement of the tailstock structure, castor wheels 23 touch the ground and take whole weight of the tailstock structure on them and whole thing can be moved easily on the floor. The picture particularly shows an arrangement of let off driven from main machine via a chain wheel output. Same holds equally good for warp tension sensing arrangement. A spring type arrangement is shown in diagram which also needs no dismantling of just one connecting link and tailstock structure is ready to go.

Description on Diagram 6 - Front View of tailstock structure

Again the numerals are repeating from earlier diagrams as they resemble same parts. The diagram shows the front of tail stock structure as separated from the machine.

Description on Diagram 7 - Back View of Full machine (head Stock + tailstock structure)

Diagram 7 shows only those numerals which need attention during removal or reassembly of tailstock structure in an event of beam change. Those are described in working below. Primary embodiment example of Working of Express Beam Change Device:

To remove the tailstock structure from the head stock following parts are to be dismantled. This following is description as a primary embodiment; however the alternative embodiments are briefly touched wherever essential in following text.

1. The chain drive to the beam numbered 38, (in alternative embodiments of this invention this can be even simple in case of dedicated motor for let off wherein only electrical connector to the motor needs to be separated from socket, there can also be gear drive, shaft drive alternatively.)

2. Snap on type Quick links numbered 24 and 25, connecting shedding levers from head stock to bottom harnesses on the tailstock structure

3. The positive easing or tension sensing levers numbered 12 on both sides by means of total two bolts. (Parallel to this in an alternative embodiment of this invention, in case of non positive easing electrical type tension sensing arrangement you need to remove only he wires connector.)

4. Six bolts at four corners of the tailstock structure at places numbered 21 and 24.

Collectively this is a job of much less than 10 minutes for two persons. The new tailstock structure with pre-drawn threads, lease rods, drop wires must be kept ready offline. This structure will go in to the machine, above 4 items are installed back in. Then the reed is to be mounted on reed holder. Threads to be joined to tail ends of exhausted beams in groups, this will take another 10 minutes and machine is ready to go into fabric production again. No lifting of frames, no frame locking procedure or nothing of that kind. Even the back and front supports for frames come pre set on the tailstock structure. With skilled operators, the machine is ready to go back in to production within in just 15 to 20 minutes.

Description on Diagram 8 -Tailstock shown with reed holding equipment for drawing-in (shown with full beam)

Figure shows tail stock structure for utilization as a drawing-in arrangement for new warp beams. As can be seen from the diagram no changes are needed in the tail stock structure except addition of brackets numbered 44 which are mounted on the very same places numbered 45, where the tail stock is clamped to the head stock upon union of the two. Brackets 44 have two projections, the first one is on front numbered 46 for mounting the reed at suitable angle for drawing in and another is towards upper side numbered 47 which is for mounting of a yarn guiding rod or pipe. Further the front projection 45 has two transverse supports numbered 48 for mounting of reed on which reed numbered 49 is mounted and clamped for drawing in. The upper projection numbered 47 has a suitable mounting place 50 for a yarn guide pipe numbered 51 which is either square or round in nature. Shown as numbered 52 are heald frame leveling plates which are pressed inwards and clamped to support the heald frames in a leveled position so that the eyelets of the heald wires from all the heald frames are aligned in a single plane for drawing in. Also shown as numbered 53, are positive easing or tension sensing levers in parked condition which also park tension sensor roller in a firm position until the tail stock is mounted back on the machine for weaving.

In this fashion the tail stock structure integrates drawing-in operation to its already enhanced utilities and this is a prominent feature of this invention, which are :

1) Holding the beam and many parts for weaving on the weaving machine

2) Reduce down time by facilitating fast changing of beams by offline preparatory

3) Transportation of beams and heald frames to the weaving machine and away

4) Eliminate need of separate drawing-in stand

From the description above and notes on working of the apparatus, it is clearly demonstrated that all the main and additional objectives of the invention are fully complied with.

Claims

CLAIMS: The embodiments of the invention in which an exclusive property or privilege is claimed in connection with articulations of this invention in textile weaving machines are specifically defined as follows:

1. It is claimed that the invention comprises a split tailstock structure of a weaving machine as illustrated in diagrams 3 to 8, the tailstock structure frame construction (1), between 400x500 mm and 1500x1700 mm in size and having length as per width of the machine, suitably made from either sub frames or by fabrication from hollow steel section of round/square/elliptical/rectangular section, hollow section contained of between 40x40 to 80x80 mm, with wall thickness between 2 and 8 mm, or the combination of these two, having heald frame guides (2), and entire shedding under-motions integrally mounted on it by means of brackets (3 and 4), further this entire tailstock structure is split from a near vertical plane from the rest of the weaving machine and having sets of castor wheels (23), at least three in number and located appropriately for weight distribution of the beam and frames, intended to enable easy movement of the tailstock structure on the weaving shop floor by self and without needing any additional lifting device or space as this is split in almost a vertical plane.

2. It is further typically claimed in detail that this invention comprises integration of shedding under-motion (26 & 27), heald frame driving links (37), heald frame guides (2) and entire mechanisms related with back end of a weaving machine, namely Back rest rollers (6 & 7), tension sensing whip roller (8), warp stop motion mounted at (9), lease rod mounting position (10) in a near normal working condition and stature, which attains a plug-in / plug-out type ease of operation in an instance of beam replenishment, one of the most significant features of this invention being the integration of shedding under motions of heald frames on the tailstock structure and elimination of the need to directly release/unlock the heald frames from their shedding harnesses or under-motions avoiding their "free fall" and the complications arising thereof.

3. Further to claim 2 above, It is additionally claimed in detail that the shedding harnesses are contained integrally in to the tailstock structures by means of two rigid bracket projections (4) in diagram 3 of 8 in patent illustrations in such a manner that they are either bolted or riveted or attached by permanent metal joining process to the tail stock structure and form an integral part thereof upon assembly and move in unison with the tailstock structure all the time and support the heald frames in their bottom most position allowed unless intermediately supported by leveling plates (32 & 33) described in claim 7 below. .

4. It is additionally claimed that the tailstock structure described in claim 1 above has the arrangement for beam mounting within tailstock structure on both sides securely, by means of at least three points of rolling bearing contacts (34) externally in a groove over beam pipe, so arranged that two brackets (15), which are in pair on each side of the tailstock structure, intended to serve purpose of beam pipe guiding, on both sides levers (16), which form third point for locking both ends of beam pipe (17), this lever (16) is pivoted in frame in such a way that it can swing out to take exhausted beam and get back on locking the new one, end caps (18), about 100 to 200 mm in diameter, either made integrally on the pipe itself or by mounting a suitable grooved adaptor (18), by either bolting or by permanent metal joining processes on the beam pipe, and this entire set-up greatly reduces the friction when beam is un-wound or rotated and this makes it a bracket-less, open-axis beam mounting arrangement, which is another unique arrangement of beam holding system with easy and quick beam unloading and loading in to the tailstock structure.

5. It is furthermore claimed that there are set of aligning and parking slides (20) provided on the tailstock structure, the mating parts (35) of which are fixed either to the ground or to the headstock split part of the weaving machine or both, which facilitate two important purposes firstly, to bring the entire tailstock structure in a lateral alignment with the head stock structure and secondly when sliding in towards the head stock structure, the sloped and raised projections on these slides serve the purpose of lifting of the entire tailstock for a vertical alignment with the head stock, along with the castor wheels (23) getting off the ground, in an engaged position, in such a manner that the tailstock structure cannot be moved easily unless it is forcefully pulled back to a position where the tailstock gets lowered off the slopes of the projections on the slides and the castor wheel touch the ground and bear entire load of the tailstock structure on them enabling free movement on the shop floor.

6. It is additionally claimed that at least four farthest located mounting and fastening points (21 & 22) on the tail stock structure, which upon clamping make the entire tailstock structure firmly locked for operation with the head stock structure, with these mounting points (21 & 22) which arranged in such a way that the points are not only easily accessible and are in such a position so as to absorb and distribute all the forces and stresses imparted by the warp threads are transferred directly to the head stock structure of the weaving machine during weaving operation, further the tailstock structure is so arranged that the upper mounting places of this structure can be utilized for mounting reed holding bracket (44), as explained in claim 9 below can be installed, and after such drawing-in operation, tailstock structure cannot mount on machine without these brackets (44) the tail stock structure.

7. It is typically claimed that although, in above embodiment mounting points (21 and 22) are almost on one plane, alternative or additional clamping points for this tailstock structure can be provided at the bottom near the parking slides (20) as an articulation of the embodiment which will serve as additional rigidity to this entire structure while weaving relatively heavy fabrics on the machine, although not shown in any of the diagrams, the inventor particularly intends to protect this additional claim.

8. It is claimed that the tailstock structure explained in claim 1, has a simple arrangement of sliding plates and slots (32 & 33), described in patent illustration diagram 3 of 8, to be shifted inwards towards the weaving-width-wise center of the tailstock structure, which holds all the heald frames in either upper or central or lower and leveled position thus same structure can be used for drawing-in of threads by means of at least two suitable reed holding brackets of shape and nature further explained in claim 8 below, enabling same tailstock structure for thread drawing-in operation when away from the weaving machine as a part of "off-line" preparatory, this is another distinct unique feature achieved and integrated within the tailstock structure for bringing in multi-functionality.

9. It is furthermore claimed that as an alternative embodiment of this invention the function of plate (32) referred in diagram 3, and locking position (52) of which is shown in diagram 8, can be attained alternatively in a more safer interlocked manner at the bottom by providing a separate and fixed locking pin for all connecting links (24) where in the operator will unlink all connecting links one by one from the output drive levers of shedding device of the weaving machine head stock and load them on a stationary or fixed pin provided on the tail stock frame structure which are arranged in such a manner that upon loading all links on the fixed or stationary pins, all healds are leveled, and hazard arising of accidental engagement (52) of plate (32) in normal weaving conditions avoided by eliminating plate (32) altogether, by a safety interlock in this alternative embodiment as connecting links can either connect to output drive lever of the shedding motion or get so to say idle by locking on to stationery pin, hence establishing a safety interlock.

10. It is furthermore claimed that no changes are needed in the tail stock structure except addition of brackets (44), which are mounted on places (45), brackets (44) have two projections, the first one is on front (46) for mounting the reed at suitable angle for drawing in and another is towards upper side (47) which is for mounting of a yarn guiding rod or pipe, further the front projection (45) has two transverse supports (48) for mounting of reed on which weaving reed (49) is mounted and clamped for drawing in, and on the upper side projection (50) has a suitable mounting place for a yarn guide pipe (51), which is either square or round or elliptical or rectangular in nature, again shown are heald frame leveling plates (52), which are pressed inwards and clamped to support the heald frames in a leveled position so that the eyelets of the heald wires from all the heald frames are aligned in a single plane for drawing in, also shown as (53) are positive easing or tension sensing levers in parked condition which also park tension sensor roller in a firm position until the tail stock is mounted back on the machine for weaving and this completes the drawing-in setup of the tail stock. It is finally and significantly claimed that with contents of all of above claims, the innovative tail stock structure is multifunctional and integrates many operations and utilities to its already enhanced utilities and these are the most prominent feature of this invention, which are as stated below: a. Holding the beam and many parts for weaving on the weaving machine b. Reduce down time by facilitating fast changing of beams by offline preparatory c. Transportation of beams and heald frames to the weaving machine and away d. Eliminate need of separate drawing-in stand
