An improved tier sheet and method for producing the same. The tier sheet is suitable for use in conveying receptacles such as cans and bottles with palletizing and depalletizing operations and it can allow the smooth sliding of receptacles in loading and unloading and can avoid the slipping off of receptacles during conveying operation. The tier sheet comprises a first zone having a first frictional resistance and a second zone having a second frictional resistance, wherein the second frictional resistance is lower than the first frictional resistance. The method of the invention comprises a feeding means to feed a tier sheet material, a forming means to form the first zone and the second zone, and a cutting means to cut the formed tier sheet.

Tier sheets

Apparatus for manufacturing sheets

A method of manufacturing pallets from sheets of substantially the same dimensions as the dimensions of the pallets to be manufactured by the steps of sequentially feeding sheets of a predetermined polygonal shape, cutting substantially at one time a plurality of corner portions of the thus fed sheets to obtain pallets and then discharging the thus obtained pallets. Belt conveyors sequentially feed sheets of a predetermined polygonal shape and cutting dies cut substantially at one time the rear corner portions of the preceding sheet and the front corner portions of the following sheet to obtain pallets and belt conveyors sequentially discharge the thus obtained pallets. When a ruled line, that is, an elongate recess or the like for bending is needed in the resulting pallets, cutting of the corner portions and formation of the ruled line are effected substantially at one time.
