摘要： In combination, a dispensing table (10) and a cushioning conversion machine (12) which is slidably mounted to the table (10). The table (10) includes a substantially horizontal work platform (14) and the machine (12) is situated below the platform (14). The cushioning conversion machine (10) includes conversion assemblies (50, 52, 54, 56, 58) which convert stock material (S) into a cushioning product (P). The cushioning conversion machine (12) is slidable to an operating position whereat the cushioning product (P) is deposited on the work platform (14) during operation of the machine. Preferably, the machine (12) is also slidable to an upstream position whereat its upstream portion projects outwardly from the table (10) and loading and threading procedures can be easily performed. Additionally or alternatively, the machine (12) is preferably slidable to a downstream position whereat its downstream portion projects outwardly from the table (10) and inspection and maintenance may be conveniently conducted on certain components of the machine (12).

摘要： A cushioning conversion machine (20), which converts stock material (11) into cut sections (P) of dunnage, includes a cutting/aligning assembly (56). The cutting/aligning assembly (56) comprises a moving blade unit (73) which is mounted on the frame (36) in such a manner that it travels between a rest position and a cutting position whereat it cuts a dunnage strip (5) (which is emerging from a dunnage outlet opening (48)) into a cut section. The cutting/aligning assembly (56) also includes an automatic alignment device (80) which automatically aligns the cut section with the dunnage outlet opening (48) when the blade unit (73) is moved from the cutting position to the rest position. The automatic alignment device (80) is unattached to the moving blade member (72) but travels therewith during jamfree operation of the cushioning conversion machine.

摘要： A machine for making a packing/cushioning pad from a stack of paper sheets in a web (M) fed by a pair of vertically aligned wheels (8, 11) and joined together by a second pair of wheels (14, 17) after having been creased transversely between the two pairs of wheels (8, 11, 14, 17). The feed wheels (8, 11) rotate at a substantially higher speed than the joining wheels (14, 17) and thus cause transverse creasing of the material (M). The machine is provided with means for measuring the length of the resulting web of material (M), which means comprise a device (c, 40) for measuring the angular distance covered by one of the pairs of wheels (8, 11, 14, 17), and an electronic device (uc) for correcting the angular distance to be covered in order to give the actual resulting linear web length.

摘要： In a machine for making packaging material, paper is pulled off a roll (12) by two pairs of spaced rubber nip rollers (20A), the lower ones of which rollers are driven. The edges (28) of the paper roll over as the paper passes through the former and the rolled paper is pushed into a pair of meshing gear wheels (24) in order to hold the rolled dunnage together loosely. A pair of blades (33A and 33B) cut the dunnage to the required length after it has passed through the gear wheels (24).

摘要： Cushioning conversion machines and methods are provided for converting plural layers (56, 57, 58) of a sheet-like stock material into a dunnage product. The plural layers (56, 57, 58) of the stock material are shaped into a three-dimensional strip of dunnage and the overlapped edge portions of a first layer (56) of the stock material are connected together separate from a central portion of the first layer (56). The overlapped edge portions of the first layer (56) may be generally coplanar with its adjacent unoverlapped portions. The overlapped edge portions of the first layer (56) may be connected together separate from other layers of the sheet-like stock material. Alternatively, the lateral edges of the other layers of the sheet-like stock material may be connected to each other and also the lateral edges of the first layer, but not to the respective central portions of the layers.

摘要： A cushioning conversion machine, method and product characterized by a connecting assembly that provides a mechanical interlock between overlapped portions of sheet-like stock material to prevent 'unzippering' of a low density cushioning product produced by the cushioning conversion machine. The connecting assembly comprises a pair of rotatable stitching members, a first one (102) having a plurality of radially outwardly extending projections (120), or teeth, around the circumference thereof, with the projections having at least two axially spaced apart segments defining a recess therebetween. The second stitching member (100) includes at least one axial punch segment (132) which includes a peripheral edge portion dimensioned to be received in the recess in the first stitching member during rotation of the stitching members. The peripheral edge portion is cooperative with the projections of the first stitching member to produce at each corner edge thereof a row of slits in the overlapped portions of the sheet-like stock material, thereby forming at least one row of tabs for interlocking the overlapped portions of the stock material. The second stitching member may include another axial segment relatively adjacent the punch segment, such other axial segment having a plurality of radially outwardly extending projections (120) meshing with the projections of one of the axial segments of the first stitching member. The stitching members may be formed by a plurality of flat disc members stacked side-by-side with the several axial segments being formed by one or more of the flat disc members.

摘要： A cushioning dunnage conversion machine (20) for converting sheet-like stock material, such as paper in multi-ply form, into cut sections of relatively low density pad-like cushioning product is provided. The machine (20) is designed so that it may be used with packaging systems requiring both horizontal and vertical positioning of the machine (20) and to this end the machine frame (36) includes a base plate (43), a first end plate (44) extending generally perpendicular from an upstream end (38), and a second end plate (46) extending generally perpendicular from a downstream end (40). The machine (20) may also include a post-cutting constraining assembly (58) for circumferentially constraining the cut sections of the pad-like cushioning dunnage product and/or a pivot cover (110) to aid in the manual threading of the machine (20). The present invention also provides packaging systems (320, 400 and 500), which include at least one cushioning dunnage conversion machine (20) positioned in a vertical manner.
