Abstract: A universal tape applying apparatus for applying tape to both sides of a butt joint formed in a running web and between a new web and an expiring web. The apparatus includes a top tape applying roll assembly and a bottom tape applying roll assembly, each roll assembly having a tape roll in the form of a cylinder with a flat side or section on its outer periphery and a tape carrier spirally mounted on the remaining portion of the outer periphery of the tape roll at an angle conforming to the angle of the butt joint splice. The tape rolls are accelerated to the speed of the running web by air cylinders which are preloaded and pressurized to provide a thrust (torque) force to thereby accelerate the tape rolls to the speed of the running web. The air cylinder for the top tape roll is released on a given signal to provide a thrust force to the top tape roll through a pawl and ratchet assembly. Release of the air cylinder for the bottom tape roll is synchronized with the movement of the top tape roll through a mechanical linkage to provide a thrust force through a ratchet and pawl assembly.

Abstract: An electropneumatic transducer having a pneumatic pressure regulator operatively controlled by a solenoid, an adjustable spring biasing assembly connected to the regulator and solenoid to maintain the moving parts of the transducer in a normally closed position and to minimize vibratory motion induced in the moving parts. A diaphragm arrangement is connected to respond to the output pressure of the regulator to introduce an additional force to the force of the solenoid. The inherent friction of the solenoid is reduced by a linear bearing arrangement. A pneumatic web tensioning system utilizing such an electropneumatic transducer.

Abstract: An assembly for holding a doctor blade in adjustable position with respect to the printing cylinder. An air loaded clamping device locks the doctor blade firmly in operative position in its holder and when the doctor blade is to be removed, the air load can be relieved and the doctor blade and its mounting quickly and easily withdrawn in an endwise direction from the printing equipment without disturbing any of the other printing equipment. The adjustment also includes an air load device for urging the doctor blade against the cylinder with a predetermined amount of pressure; this biasing of the blade into proper engagement with the cylinder is made by the air loaded device and through an adjustable gear; the adjustable gear in turn, can be adjusted initially to make the proper preliminary adjustment of the blade relative to the printing cylinder.

Abstract: 1282256 Joining webs ZERAND CORP 13 March 1971 6836/71 Heading B8R Apparatus for applying splicing tape to a butt joint formed between a new web and an exhausting web comprises a first roller 38 for automatically applying tape to the top of the splice and a second roller 38a for automatically applying tape to the bottom of the splice, the rollers 38, 38a having carriers 64, 64a upon which the splicing tape is mounted (Fig. 6, not shown). The rollers 38, 38a are formed with flats 40, 40a to provide clearance for the web during normal running and are respectively associated with a pawl and ratchet assembly (76, 76a) and an air cylinder assembly (78, 78a, Figs. 2 to 4, not shown) which, when actuated, accelerate the rollers to the speed of the running web, this actuation being effected by appropriately disposed sensors responsive to the presence of a metal knife secured to the leading edge of the new web. The rollers 38, 38a are synchronized through a mechanical linkage (Fig. 2, not shown) and cooperate with pivotally mounted nip rollers 68, 68a during the tape-applying operation.
