Abstract: ABSTRACT         A novel protease product suitable for admixture to washing compositions and exhibiting substantially attenuated allergenic properties is prepared by cultivating strains of Bacillus licheniformis which have been mutated to block their synthesis of proteases other than Subtilopeptidase A (subtili-sin). The commercial Bacillus licheniformis derived protease products are mixtures of subtilisin and a non-serine protease of lower stability and greater allergenicity than subtilisin.

Abstract: Abstract:    An arrangement for wrapping big web rolls comprises a support system for supporting and rotating a web roll and a frame surrounding the web roll and having means for leading a wrapper around the roll.  The frame includes a guide strap and operating means for applying the strap onto the outer surface of the roll and for keeping the wrapper between the strap and the roll.  The operating means has a support position, in which it supports a por-tion of the guide strap at a distance from the roll, thereby causing the guide strap to depart at a predeter-mined point from the surface of the roll.  For causing the leading end of the wrapper to follow the roll, the operating means can be moved around the roll.  In this way the departure point of the guide strap moves around the roll causing an increasing portion of the guide strap to contact the outer surface of the roll to keep the wrapper closely thereon when rotating the roll during simultaneous feeding of the wrapper thereto,
