Abstract
An endcap for simultaneously dispensing and hemming film from a roll while an operator is wrapping a load. An endcap is inserted into each end of a roll of film and an operator manually dispenses the film. The endcap includes an insert, a base, and a flange that hems the film. The flange is angled outwardly from the base of the endcap and overlaps an end portion of the roll so that when the film is dispensed, the edges of the film are hemmed.
Claims20
An endcap for dispensing and hemming film from a roll, said roll having opposite ends and a tubular core defining an inner diameter, said film being wrapped around said roll thereby defining an outer diameter, comprising:
- an insertion means having a hollow interior and concentrically engaging said inner diameter of said roll;
- an end abutting means integral with an outer end portion of said insertion means for abutting an end of said roll;
- and
- a hemming means integral with said end abutting means for hemming said film as it is dispensed from said roll.
An endcap for dispensing and hemming film from a roll wherein said roll has opposite ends and a tubular core defining an inner peripheral surface having an inner diametrical extent, and said film is wrapped around said roll thereby defining an outer peripheral surface having an outer diametrical extent, comprising:
- cup-shaped means for axial insertion into one end portion of said tubular core of said roll whereby sidewall portions of said cup-shaped means engage said inner peripheral surface of said tubular core, and a hollow portion of said cup-shaped means opens outwardly from said one end portion of said tubular core so as to be capable of receiving fingers of an operator using said endcap for dispensing film from said roll;
- end-abutting means integral with an axially outward peripheral portion of said cup-shaped means for abutting an end portion of said roll;
- and
- flange means integral with said end-abutting means and overlying said end portion of said roll for hemming said film as said film is dispensed from said roll.
An endcap for dispensing and hemming film from a roll, the roll having opposite ends and a tubular core defining an inner diameter, said film being wrapped around said roll thereby defining an outer diameter, said endcap comprising:
- an insertion means for engaging the inner diameter of the roll, said insertion means having a hollow interior;
- an end abutting means integral with said insertion means for abutting an end of the roll, said end abutting means having a diameter greater than the outer diameter of the roll, and
- a hemming means for hemming the film as it is dispensed from the roll, said hemming means being a flange overlapping an end portion of the roll and integral with the periphery of the end abutting means and angled outwardly thereof.
An endcap for dispensing and hemming film from a roll comprising:
- a central section for engaging an end portion of the roll and centering the endcap with respect thereto;
- an annular section extending outwardly from said central section for overlying an end of the roll, and
- an annular flange joined to and flaring from an outer margin of said annular section for overlying an end portion of the roll and forming a hem as film is paid out from the roll.
