The fourth wedge-shaped segment 92 is then disposed on the drum core adjacent the section 58, and the third wedge segment 98 is disposed between the wedg• 92 and IP。e first semi-cylindrical section 82 for completing the alternate rise grooving system on the drum。
Conventional Rise—Bias Cross-Over Grooving 5ystem
The conventional rise—bias cross-over grooving sys- tem is substantially identical with the conventional rise grooving system and is depicted in FIGURES 12 through
15。 Substantially the only difference bet'veen the two con- ventional rise grooving systems is that the standard or straight conventional rise hereir。before set forth is pro- vided with cro!ss-over s•ctions or areas disposed substan- tially longitudinally on the drum core in alignment with the longitudinal axis thereof。 On the other hand, the conventional ri•e—bias cross-over grooving is provided with a cross-over s•ction or area which is canted or o8- set with respect to the longitudinal axis of the drum core。
In order to provide the conventional rise—bias cross- over grooving system on a drum core, the desired par- alter grooved sleeve 18 is se1ect•d and is cut and re-as- sembled on the drum core as follows:
The sleeve 10 is cut or slit along the canted lines 100, 102, 104 and 106, and in addition, is cut along the sub- stantially longitudinal lines 188 and 110。 Prior to the slitting operation, a complete groove 112 is removed be- tween the lines 180 and 102。 This cutting operation pro- vides the sediments IU, 116, 118, 120, 122 and 124。 The severed segments may be separated and re-arranged in the manner as hereinbefore set forth whereby the wed;;e segments 116 and 118 are intercham。ged between the semi-cylindrical sep• rents 114 and 120, and the wedge seg- ments 122 and 124 are simiiarly interchanged between the semi-cylindrical sections 120 and TU, as shown in FIGURE 13。 Th>• usual end filler bars 126 and 125 are disposed adjacent the drum flanges 130 and 152, as here- inbefore set forth, and the conventional rise bias cross-
the parallel grooved sleeve 10 of the desired diameter is
- selected, and is cut and re-assembled on the drum core in the manner hereinbefore set forth。 OF course, it is necessary to cut the sleeve 10 slightly differently to pro- vide this type of yooving。
The cylinder 10 is slit or cut longitudinally along the lines 68, 70, 72 and 74 as set North in the previous em- bodiment。 One full groove 76 (FIGURE 8) is removed from th• sleeve 10 between the cuttin(; lines 68 and 74 prior 。to the s1iitinp• or cutting operation。 In addition, the sleeve 10 is cut or slit along the canted or diap•ona1 lines 78 and 88, thus pifiinp• the cylinder 10 into several se;;ments, namely: a substantially semi-cylindrical por- tion 82, a first wedge-shaped segment 84, a second wedge- shap•d segment 86, a second substantially semi-cylindrical section 58, a tifird wedge-shaped segment HO, and :i fourth
40 over grooving system may be provided on a drum core。
Alternate Rise—Bins Cross-Over Grooving 5ystem
The alternate rise—bias cross-over grooving system is substantially identical with the alternate rise grooving
65 system and is depicted in FIGURES 16 throu¿;h 19。 Sub- stantially the only difference between the two alternate 开槽电缆线筒体的方法英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_100039.html
