Abstract
A flat compressible material is roll-formed into a cylindrical package by a belt drive. The diameter of the rolled package is controlled so that a fixed predetermined length of material forms a rolled package of a predetermined diameter. The length of belt drive in contact with the material is proportionate to the length of the material fed into the belt drive, and holds the finished package size to a predetermined diameter.
Claims32
A method for controlling the diameter of a rolled package of compressible mat material comprising the steps of feeding said material into engagement with a belt moving along a path defined by its length, said belt defining a roll-confining collection region for rolling said material into a package and from which said package is subsequently released, controlling the rate of said belt upon engagement of the said material with the belt and upon disengagement from said belt at the collection region, controllably altering the said rates of engagement and disengagement of said belt with the said material from the time of engagement of the said material with the said belt, determining when the said rolled package has reached a predetermined size and releasing the said package from the said collection region whereby a desired size rolled package is produced.
An apparatus for controlling the diameter of a rolled package of compressible mat material comprising a belt, said belt having a portion defining a roll collection region, means for moving said belt along a path defined by its length, means for feeding said material into engagement with said belt, means for engaging said belt with said material and means for disengaging said belt from said material at the collection region, means for controllably altering the rates said belt engages said material and disengages from said material from the time said material is fed into engagement with said belt, means for determining when the said rolled package has reached a predetermined size, and means for releasing said package whereby a desired size rolled package is produced.
An apparatus for controlling the diameter of a rolled package of compressible mat material comprising a belt, said belt having a portion defining a roll collection region, means for feeding said material into engagement with the said belt, roll collection region means for engaging the said material with the said belt at a first region, means for disengaging the said material from said belt at a second region, means for controllably displacing the said means for engaging and disengaging in a radially outward direction from the time said material is fed into said belt, means for determining when said package has reached a predetermined size and means for releasing said package from said belt whereby a desired rolled package is produced.
