Abstract
An assembly for the automated production of conical paper sleeves for plants uses paper stock precut in a trapezoid configuration which is continuously fed to the assembly. The precut sheets are folded diagonally twice to form a conical sleeve. The folding process includes application of an adhesive on the overlap of the folded sides to securely seal the sleeve. The precut sheets are transported along the assembly via a series of belts, rollers and electrical motors. The synchronization of the folding process and the application of adhesive is electronically monitored and controlled.
Claims13
An automated plant sleeve production assembly for forming a conical paper plant sleeve from a precut sheet of paper stock, said assembly comprising:
- a lifting table on which a plurality of precut sheets of paper stock are initially staged, said lifting table positioned at an angle proportional to a taper of a first fold of the precut sheets,
- at least one feeding roller transfers each precut sheet from said lifting table onto a first table,
- a sensor activates said at least one feeding roller,
- at least one belt on said first table transports each precut sheet along said first table,
- a folding guide on said first table forms a first 180 degree angle fold in each precut sheet,
- at least one lifting roller transfers each first folded precut sheet from said first table to a transfer section interconnecting said first table to a second table,
- said second table connected to said transfer section at an angle which is proportional to a taper of a second fold of the precut sheets,
- an adhesive applicator disposed on said second table, said adhesive applicator applies an amount of adhesive onto a surface of each first folded precut sheet such that said adhesive is applied coincident with a line of symmetry of each first folded precut sheet,
- a folding guide on said second table forms a second 180 degree angle fold in each first folded precut sheet, thereby forming a conical configuration of the conical paper plant sleeves, wherein the sleeves are transported through at least one creasing roller where pressure is applied to bond said amount of adhesive, thereby forming the conical paper plant sleeve from the precut sheets of paper stock, and
- a receiving basket into which the conical paper plant sleeves are deposited.
