new stainless steel food safe seamer the 10a can seamer is a modern all stainless steel single head semiautomatic can closer designed for compliance with food safety and hygiene standards and providing exceptional double seaming integrity of tinplate, aluminium, paperboard or plastic cans and ends. a double seam is formed in two operations, with the first operation doing ninety per cent of the work. uniquely the 10a rotates the can thirteen times during this first operation to achieve optimum first operation seam specifications, before the second operation finishes the process of tightening the seam. with the food industry striving to use thinner and lighter weight can ends, it is imperative that the maximum number of first operation revolutions is employed so that the end hook can be formed smoothly to achieve the desired level of lowamplitude wrinkles. filled cans with the loose end or closure on top are placed on the lifter plate by the operator, who then presses the twin safety buttons simultaneously with each hand to start the pneumatic actuation. the lifter raises the can to clamp it to the driven seaming chuck and the can starts rotating in the industry preferred clockwise direction which is beneficial to the formation of the double seam. a second pneumatic cylinder then automatically actuates the trigger mechanism to initiate the double seaming cycle, and then the lifter lowers, allowing the operator to remove the seamed can, and place the next one in position. to comply with the criteria for washdown certified food packaging equipment, the frame fabrication, safety guarding and mechanical parts are manufactured from food grade 316 stainless steel, with the tooling including the seaming cam manufactured from vacuum hardened 440c martensitic stainless steel. the 10a can be washed with the same cleaning agents as used on a can filler.  the first and second operation seaming rolls are mounted on double row angular contact sealed for life ball bearings. bearing replacement is cost effective and easy. grease lubrication is used throughout the seamer with food grade grease specified as standard.  1st and 2nd operation seam adjustments are facilitated by easy access adjusting screws in the top of the seaming head assembly. seaming roll height is simply set using the threaded seaming roll pin and lock nut. pin height is set using a fine threaded adjuster on the lifter shaft sleeve, and base pressure is changed with the aid of an integral pressure adjusting nut on the lifter spring holder.  the seaming head assembly is raised and lowered for can height changes using a handwheel mounted on a lead screw assembly. can diameter changes are as simple as changing the seaming chuck, and resetting the seaming rolls. it may also be necessary to change seaming roll assemblies and the lifter plate depending on the can design and specification. all can size changeovers can be accomplished within fifteen minutes or less.  the 10a seamer is a modern food safe cost effective can closing machine designed to work with light weight cans and ends to achieve optimum double seam integrity.  speed up to 10 cans per minutecan diameter range 52 153 mmcan height range 50 300 mmelectric power 1.1 kwcompressed air 5 barweight 175 kg
