Abstract

A strap seal joint and method for applying a seal to the overlapping ends of a strap about a bale of resilient material are disclosed. The bale is initially restrained against expansion in a press. The strap is provided with two oppositely facing major side surfaces having predetermined frictional characteristics. The strap is looped around the bale to overlap inner and outer and end portions of the strap. The seal is applied to the overlapping end portions of the strap. The seal and one of the strap end portions are in an interlocking engagement sufficient to prevent withdrawal of the strap end portion from the closed seal. The seal is also crimped against the other strap end protion with a predetermined degree of frictional force engagement which is sufficiently great, in combination with other frictional forces acting on the strap, to at least initially restrain the strap other end portion relative to the seal at least until the press is opened but which is sufficiently low to permit relative movement between the overlapping strap end portions when the tension force on the strap exceeds a predetermined tension force.
