Claims3
A bag opener for opening a sequence of bags having a non-uniform external contour, said bag opener comprising:
- an articulated elongated heated member having a region at a temperature sufficient to melt said bags having said non-uniform external contour, said articulated elongated heated member being pivotally supported to contact and follow said non-uniform external contour at different portions of said non-uniform external contour;
- and
- an assembly that brings said sequence of bags having said non-uniform external contour into contact with said region such that said bags having said non-uniform external contour are opened as said bags having said non-uniform external contour contact said region without stopping movement of said sequence of bags.
A bag opener for opening a sequence of bags having a non-uniform external contour, said bag opener comprising:
- at least one articulated elongated heated member having a region at a temperature sufficient to melt said bags having said non-uniform external contour, said articulated elongated heated member being pivotally supported to contact and follow said non-uniform external contour at different portions of said non-uniform external contour;
- and
- a conveyor that brings said sequence of said bags having said non-uniform external contour into contact with said region such that said bags having said non-uniform external contour are opened as said bags having said non-uniform external contour contact said region without stopping movement of said sequence of bags.
