  • Patent number: 8388508
    Abstract: A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side crumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage.

  • Patent number: 5947467
    Abstract: A decurler has an arched plate and a rotatable paper sheet feed roll defining an adjustable gap through which paper sheets driven by the roll exiting a copier or printer apparatus which causes the paper sheet to be curled transversely of the feeding direction, and the gap is selectively adjusted to control the decurling effect dependent upon the extent of the curl in the paper induced by the copying or printing process.

  • Patent number: 5871434
    Abstract: A device for stiffening workpieces of paper includes elements that provide the workpieces with an undulated profile. The elements may be in the form of freely rotatable disks or belts that revolve around freely rotatable rollers. Respective sections of the disks or belts which come in contact with the workpieces extend through a common central plane in such a way that they provide the workpieces with an undulated profile. In order to prevent the profiling elements from laterally displacing the workpieces, a conveyor is provided which clamps the workpieces between respective conveyor sections.

  • Patent number: 5836862
    Abstract: A paper dispenser includes a housing having a controlled-stroke hinged device mounted onto a reel-holder. A protective housing cover features longitudinal ribs fitting the stroke hinged device such that, when the cover is closed and the stroke-hinged device lowered in position, an extending paper length the user pulls on is folded with the long ends partly under the paper band being fed out by the upper contact of the stroke hinged device so that it may be introduced folded between the drum and a tensioning device, be severed by a paper-cutoff device, folded, and then be pulled out as a folded napkin or towel by the user. Alternately, and when the stroke hinged device is moved into a raised position relative to the reel-holder and an assembly consisting of the drum and the tensioning device, the paper is fed unfolded between the drum and the tensioning device, to be severed by the cutoff device when pulled onto by the user.

  • Patent number: 5727367
    Abstract: Packaging material, particularly for forming blanks for hinged lid packets, is delivered to a packaging machine in web form and at least one creasing or shaping operation is performed (44; 112) on the web (2) prior to severing individual blanks (50) from the web. Folding or wrapping of a blank around an article to be packed in the machine is monitored and the creasing or shaping operation varied to optimise machine performance: for example, an adjustable creasing tool can be adjusted to compensate for tool wear. Individual blanks are inspected for longitudinal curl, usually caused by the web having been wound on a reel, and where necessary a correction is applied during feeding of the web, e.g. by adjusting the angle of wrap of the web around a decurling roller (38; 108).

  • Patent number: 5658228
    Abstract: A tamper evident container assembly includes a container body having a bottom wall and peripheral side wall, the side wall terminating in an outwardly curled rim. A reusable lid includes a top wall portion and a depending skirt portion, the depending skirt portion constructed of spiral wound stock and having a free end, a major peripheral portion of the free end tucked under the upper rim and upwardly into engagement with the side wall, with a minor peripheral portion of the free end left untucked to thereby provide a gripping area to facilitate tearing and removal of the tear strip. The depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about the skirt portion to thereby define an annular removable tear strip inclusive of the free end, with the line of weakening lying on the rim, between upper and lower edges of the rim.
