Description
~5~39~4 BACKGROUND OF THE INVENTION
A conventional type of dryer for webs of wood pulp includes a pllJrality of rollers. The web is air-borne as it follows a convoluted 5 path about the rollers. One difficulty associated with such pulp dryers occurs when it is necessary to initially feed the le~ding end of a pulp web through the dryer. An air-borne leader, commonly referred to as a "kite", is initially used to lead the leading edge of the web along the proper convoluted path. The leader is elongated and 10 made of a relatively light material so it is easily carried by the air which is directed to rnove the leader and the web along the proper convoluted path. The leader has pockets formed thereon to better catch the air so the leader is properly propelled along its path.
15 The leader has transversely extending stiffeners between the pockets to maintain its proper shape as it passes through the dryer.
Conventionally these stiffeners are formed by wooden rods inserted through transverse pleats in the leader material. Various problems are associated with these wooden rods. Firstly, these rods are 20 normally inserted at the pulp mill where it is considered to be a frustr~ting and uneconomical job. Furthermore, the leader must be fed into an awkward entry point of the pulp dryer as it begins to follow the path through the dryer. In the process of rapidly handling the leader it is not uncommon to break some of the rods. This can 25 ruin the attempt to feed the web through the dryer.

BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
2û Figure I is a top plan view of an apparatus for feeding a web through an apparatus having rollers and wherein the web is air-borne;
Figure 2 is an enlarged, fragmentqry plan view thereof, partly broken away;
Figure 3 is a sectional view taken along line 3-3 of Figure 2;
Figure 4 is an enlarged, fragmentary view, partly broken away, of the end of one of the rods and one of the tubes of the appqratus;
Figure 5 is a sectional view taken along line 5-5 of Figure 2, 1;~593~
Figure 6 is an enlarged sectional view taken along line 6-6 of Figure 2;
Figure 7 is an enlarged, fragmentary view, similar to Figure 4 showing qn alternative embodiment; and Figure 8 is an enlarged sectional view simiiclr to Figure 6 showing the alternative embodiment of Figore 7.
Referring to Figure 1, this shows an apparqtus I for feeding a web through a wood pulp dryer or other apparatus of the type having rollers and wherein the web is air-borne. The apparatus I includes a 15 leader 2 with a leading end 4 and a trailing end 5. The trailing end is connected to a tape 6, usually of a coarse woven fabric such as hemp or to a tail holder or clip. The tape is typically connected to a clamp which receives the leading edge of the web. As may be observed, the leader is elongated and has a plurality of transverse pockets 8 formed 20 thereon.
As shown best in Figures 2 and 3, a plurality of transverse pleats 10 qre formed on sheet-like material 1~. In this embodiment, qs shown in Figure 3, the pleats are formed by folds in the mqterial and not by 25 separate pieces of material~ The pleats form transverse passageways 1~ extending from one longitudinal edge 16 of the leader to the opposite longitudinal edge 1~. The pleats could alternatively be formed by strips of cloth sewn onto the leader to form a cloth tube at each such position.
3û
Tubes 20 are located within each of the passageways 14 adjacent each of the longitudinal çdges 16 and 1~. Two such tubes are shown in Figure 3 and one such tube in Figure 2 although it should be understood that each of the passageways has two such tubes. The ~Z5934~L
leader has longitudinal pleats 22 and 24 extending along the longitudinal edges 16 and 18 respectively. A wire 26 extends along each edge of the leader within each of the longitudinal pleats. As best shown in Figure ~, each wire 26 extends through the outer end of 5 each of the tubes 20 on eqch side of the leader. Thus the pleats 10-and wires 26 serve to fixedly connect eGch of the tubes to the leader adjacent the longitudinal edges thereof. Preferably the tubes are of metal. Alternatively, the tubes can be held fixedly adjacent the edges by sewing passageway 14 more narrowly at least at their ends so 10 the tubes are tightly held in the passageways as shown in Figures 7 and 8.
A rod 28 extends through each of the passageways 14. Each end of the rod is slidably received in one of the tubes 20. This is shown best 15 in Figure 4. It is also clear from Figures 2 and 4 that the rods each have a length which is less than the width of the leader at the longitudinal position of the rod. This permits slidable movement of the tube with respect to the rod which may occur due to shrinkage of material 12. For example, referring to Figure 4, it is clear that 20 tube 20 is capable of sliding to the left with respect to rod 28. The tube on the opposite end of the rod likewise is capable of sliding to the right relative to the rod. Wires 26 at the ends of the tubes keep rods 28 from poking through the material at edges 16 and 18. For the embodiment of Figures 7 and 8, tubes 20.1 are crimped at 21 for this 25 purpose. The material comprising the leader and the pleats 10 preferably is of a resilient material which tends to bias the tube means away from each other. Thus the leader tends to retain its full width at the position of each rod 28. When the longitudinal edges of the leader are pushed towards each other adjacent the rod, they 30 resiliently tend to return to their original position when the force is removed. This effect is accornplished by employing a woven nylon fabric or other synthetic.
Preferably the rods 28 are of spring steel or other metal dissimilar to ~S~334~
the tubes and pieces of reinforcement 30 are sewn over the longitudinal edges 16 and 18 of the leader adjacent the ends of the rods 28~ These are preferably pieces of leather or a synthetic leather substitute sewn to the leader.
As seen in Figure I, a plurality of pockets 8 are formed on the leader and are spaced-apart longitudinally therealong. The pockets open towards the trailing edge 5 anà are adapted to cqtch the air to propel the leader alona the desired path through the dryer. As shown in Figures 3 and 5, each pocket 8 has a corresponding pocket 32 on the opposite side of leader 2. In the form of the invention shown in Figures 2 and S, each pocket 8 has an adjacent pocket 34 formed on the side same of the leader such that the pockets 8 and 34 together span the complete distance between longitudinal edges 16 qnd 18. A
pocket 36 is formed on the side of leader 2 opposite eqch pocket 34.
Each of the adjacent rows of pockets 8 and 34 as well as each of the adjacent rows of pockets 32 and 36 on the opposite side of the leader are formed of material wider than the width of the leader spanned by 20 each row of adjacent pockets. This may be observed in Figure 5 where it may be seen that each pocket has a full opening. This is accomplished by stitching together longitudinal pleats 38, shown in Figure 2, on the portions of the muterial not forming the pockets.
Thus the unpleated pockets are wider to provide the full opening.
Referring to Figure 5, pockets 8 and 34 are stitched together at 40 which is a distance from the rest of the leader 2. Likewise, pockets 32 and 36 are stitched together at 42. These stitches tend to hold the pockets open to catch the air.
Referring to Figures 2 and 3, the leader 2 is formed by a plvrality of lengths of cloth sewn together. The section of the leader illustrated in these figures has a leading end 44 and a trailing end 46~ Two lengths of cloth 48 and 50 are shown in these figures. Length 48 is ~l2S934~
folded to form pleat l O to the ieft of Figure 3 and the top of Figure 2.
It then extends to seam ~2 where it is folded back to form pockets 32 and 36 and has an end at hem 54.
Cloth 50 overlaps cloth 48 between seam ~2 and its hem 56 to form pockets 8 and 34. It then extends to the right of seam 52 and is folded to form pieat IO.I to the right of Figure 3 and near the bottom of Figure 2.
The above described construction is considered to be more rugged than the conventionGI construction employing a single long piece of cloth to form the leader with the pockets being formed by patches sewn onto the leader. However, this type of construction is also within the scope of the invention.
The embodiment described above is tapered, but the invention also applies to leaders which are substantially rectangular, having paral lel si des.
The apparatus described above is employed exactly the same as other known air-borne leaders or kites. However, it is not necessary to insert wooden rods at the mill site. The slidable fit between the tubes and the rods allows for relative movement in case the longitudinal edges contact objects such as occurs when the leader happens to reach the outer ends of the rollers. This prevents damage to the leader apparatus as well as the pulp dryer.
The metal rods are significantly stronger than wooden rods and are relatively light in weight. Flexible piano wire approximately one 3û eighth inch in diameter is suitable for the rods.
