SHEET RUBBER PLAITING AND BANDING MACHINE 



This device is designed primarily to plait the edges of thin 

 rubber articles and to attach a band of rubber at the same time. 

 It effectively accomplishes such work around the limb and waist 

 openings of rubber diaper 

 covers, although it may 

 be used for ornamenting 

 other articles of wearing 

 apparel. 



The machine shown in 

 side elevation has two 

 rollers, A and B, which 

 coact, the former having 

 corrugations en- 

 tirely across its face, 

 while the latter is corru- 

 gated at the edges with a 

 plain cylindrical portion 

 D between. The inter- 

 meshing gear teeth pro- 

 duce parallel plaits or folds and include any form which will 

 produce a puckered or wrinkled surface. 



The operator passes the articles to be ornamented between the 

 rollers A and B, which are brought together by pressing the foot- 

 treadle connected to the swing-frame by a rod. A pair of spur 

 gears, which mesh together, prevents the material from being 

 subjected to a driving strain. A narrow strip of rubber is fed 

 between D and a smaller roller to insure uniform feeding with- 

 out excess tension. — James William Brundage, Akron, Ohio, as- 

 signor to The Miller Rubber Co., Akron, Ohio. United States 

 patent No. 1,371,853. 



Rubber Pl.mting M.^chixe 



A SWISS RUBBER NIPPLE 



This invention relates to a rubber nipple which is provided 

 with an inward projecting part in which a valve slit is cut. The 

 nipple is formed in one piece by dipping it in the usual way, 

 with the projecting part extended outwards. It is then partially 

 vulcanized and removed from the mold. The nipple is then 

 turned inside out, or the projecting part is pushed inwards and 

 the vulcanization is completed. This process is stated to prevent 

 the valve slit opening owing to the release of the tension due to 

 cutting. — H. Grimmelmann, Zurich, Switzerland.
