Embodiment Construction

[0053] Referring now to the drawings, first to the attached figure 1 , shows a dunnage conversion system 20 comprising a supply 22 of C-folded sheet material 24 and a dunnage conversion machine 26 of the present invention. The illustrated conversion machine 26 takes sheet material 24 from the supply 22 and converts the sheet material 24 into a dunnage product 30 having a lower density than the unconverted sheet material 24 . Exemplary dunnage conversion machines are disclosed in US Patent Nos. 5,123,889, 5,607,383, and 6,015,374, each of which is incorporated herein by reference.

[0054] The present invention provides a supply 22 of reduced width C-folded sheet material 24 for a dunnage conversion machine 26 that can be easily spliced ​​to another supply 32 of sheet material 24 and discloses the use of A method for splicing together continuous supplies 22 and 32 of such sheet material.

[0055] The C-folded sheet material 24 may comprise paper, such as kraft paper of variou...

Abstract

A supply of sheet stock material for a dunnage conversion machine that is readily spliced to another supply includes (a) one or more plies of sheet material having (i) multiple longitudinally-extending sections, including a center section bounded by lateral sections, wherein the lateral sections are folded over a common face of the center section along longitudinal fold lines at lateral edges of the folded sheet material, and (ii) a leading end and a trailing end at respective longitudinally-opposite ends of the sheet material, wherein the lateral sections are separated from the center section adjacent the leading end and adjacent the trailing end along respective lines of separation; and (b) a splicing adhesive applied to the sheet material adjacent the leading end or the trailing end on both the center section and each of the lateral sections to facilitate splicing each section to respective sections of two supplies.

Description

technical field [0001] The present invention relates to a supply of sheet material for a dunnage conversion machine, and a method of converting said supply of sheet material into dunnage products. Background technique [0002] Dunnage products are used to pack items in container shipments to minimize or prevent damage to these items during transit. Dunnage products are used for cushioning, void filling, blocking and bracing, and other packaging applications. [0003] Shipping sheet material and then using a dunnage converting machine to convert the sheet material to a lower density dunnage product at or near where the dunnage product is used, compared to producing dunnage product at a central location and then shipping the dunnage product to the end user Litter products may be more effective. A dunnage conversion machine is sometimes called a conversion machine or simply a converter. Upon initial start-up, the leading end of sheet material must be fed into the conversion ...
