a cable is 。being wound on the conventional rise groov- ing system, the cable moves through the parallel section B, into the helical or cross-over section D, throu¡;h th• parallel section C, into the helical or cross-over section fl, and back through tire para11e1 section B。 In one com- p1。ate revolution of the drum, the cable is thus directed fi’om one parallel groove of that grooving IS into the next Succe••ding or adjacent parallel groove with a smooth and efficient conool of the cattle winding operation。

Of a siZ+° complementary to the drum core is selected。 fi-s shown in FIGURE 4, th°= sleeVe 18 is cut or split in any suitable manner (not shown) along the longitudinally
60 extending lines indicated at 2$, 26, 50 and 32。 The
SleeVe 10 is also cut or split along the canted or diagonal
lines indicated at 34 and 36。 In this manner, the cylin- drical sle•-r- to is pided into several segments, namely:
a Substantially semi-cylindrical portion 35, a substantially wedge shaped portion '40 adjacent thereto, a second Wedge-Shiiped portion 42, a second substantially semi- ylindrical portion 44, a third wedge-Shaped segment 46 Similar to the portion 40, and a fourth wedge-shaped seg- ment 43 similar to the portion 42。 It is preferable tbat

when the severed portions or segments are removed or separated, as shown in FIGUltE 2, the segments 40 and
42 will be one groove shcrter than the remaining seg- ments。
The severed portions or s•gments may be remov•d or separated for re-assembly around the drum core to pro- vide the conventional rise yooving system thereon。 The semi-cylindrical portion 38 oiay be bolted or welded to the outer periphery of the drtim core with one side thereof adjacent “tne flange 14。 The second wedge portion or segment 42 is disposed adjacent the section 35 wi"tn the cutting line o4 in abutment with the cutting line 26 where- by the right hand groove 52 thereof (FIGURE 5) is in alignment or communication with the right hand groove 54 of the section 35, as viewcd in the drawings。 The first 开槽电缆线筒体的方法英文文献和中文翻译(5):http://www.youerw.com/fanyi/lunwen_100039.html
