Cutting apparatus, apparatus for manufacturing sheet material, and apparatus for manufacturing gypsum building material
A cutting apparatus is provided. The cutting apparatus includes a cutter disposed in a conveying path for conveying a plate-shaped object and configured to cut the object, a downstream conveyor disposed downstream of the cutter in the conveying path and configured to convey the object, and a foreign-matter adhesion preventer disposed between the cutter and the downstream conveyor and configured to prevent foreign matter scattered by the cutter from adhering to the downstream conveyor.
Orbital knife
An orbital knife including a support structure; a yoke rotatably attached to the support structure constituting a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls securely connected to at least one of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls and including a cutting element; one or more sun gears rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; and one or more planet gears wherein each knife roll has rotatably attached thereto at least one planet gear and each planet gear is mated with a sun gear.
Orbital knife
An orbital knife including a support structure; a yoke rotatably attached to the support structure having a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls connected to at least two of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls; one or more sun gears rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; one or more idler gears wherein each such idler gear is mated with one of the one or more sun gears; and one or more planet gears wherein each knife roll has rotatably attached thereto at least one planet gear and each planet gear is mated with one of the one or more idler gears, with the sun gear driving the idler gear which in turn drives the planet gear.
Web material application systems and methods
A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.
Method of Cutting a Running Web
A method of cutting a running web, including the steps of: training the web over a smooth peripheral surface of an anvil drum; rotating a blade that extends in an axial direction of the anvil drum about an axis of rotation that is parallel to the axis of the anvil drum; retaining the blade in a retracted position in which a cutting edge of the blade is spaced apart from the web on the anvil drum, the blade being retained against a biasing force of a pre-loading mechanism that biases the blade in a direction towards the axis of the anvil drum; and releasing the blade at a time calculated to assure that the blade will hit the web at a time when the blade passes through a plane that contains the axis of the anvil drum and the axis of rotation.
PERFORATOR LUBRICATION SYSTEM
Disclosed are apparatus, systems and methods of lubricating a knife which provides intermittently spaced cuts to a moving web, also referred to as perforations. In this manner, the apparatus, systems and methods are useful in both perforating a web and lubricating the knife used to form the perforations. the apparatus, systems and methods disclosed herein improve knife life, perforation quality and web handling.
Cutting device for cutting labels from a web of labelling material
A cutting device for cutting labels from a web of labelling material. The cutting device includes a first member rotatable having a blade and rotatable about a first axis, a second member rotatable about a second axis, and a cutting station. The second rotary member having a receiving portion to receive the blade, advancing the receiving portion around the second axis, and supporting the web. At the cutting station, the blade engages the receiving portion to cut the web covering one at a time the receiving portion. The second rotary member includes a first portion extending at a first distance from the second axis and comprising the receiving portion, and a second portion angularly spaced from the first portion and extending at a second distance from the second axis. The blade faces the first angular portion and the second angular portion alternately to one another.
DEVICE FOR PRODUCING BOOK COVERS, BOX LIDS OR GAME BOARDS
The invention relates to a device for producing book cases, box lids or game boards with a cutting mechanism, which is arranged in the region of the blank feed and serves for cutting off the blank corners, wherein each tool pair of cutting cylinder and counterpressure cylinder is accommodated in a common bearing block and the bearing arrangement of the cutting cylinder has two mutually spaced eccentric bushes and a drive element arranged between the eccentric bushes.
WEB MATERIAL APPLICATION SYSTEMS AND METHODS
A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.
Head for horizontal flow wrapper packaging machine
A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.
