Manual application is ideal for low and moderate volume users and requires little or no investment in tooling. In addition, manually applied strapping is frequently specified in light duty, high volume applications where the cost of an automated system cannot be justified. Polypropylene and polyester strapping can also be applied with battery powered and pneumatic tools using either a friction weld or a mechanical seal. A moderate investment in tooling can frequently be cost justified by seal and buckle savings in sealless tools. The next level of application utilizes semi automatic or automatic machines. When applying strapping with automatic machines, machine grade strapping must be specified. Machine grade strapping is manufactured under closer tolerances and has minimal camber. Semi automatic (archless) machines have become affordable for even occasional users, and should be specified with semi-automatic strapping for maximum cost effectiveness. Automatic machines can range from operator assisted full arch machines to fully automatic in- line systems. The general rule in specifying application methods is this: Up front expenditures in tooling and machinery will increase tension capability, consistency, and joint efficiency, while reducing costs of closures, waste and labor.
