A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a movable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

An example system includes a cutting tool and a device configured to remotely control the cutting tool. The device is configured to establish a wireless communication with the cutting tool, and the cutting tool is configured to send a first signal to the device indicating that the cutting tool is enabled to be operated remotely responsive to the cutting tool receiving information indicating that a trigger is locked in an “on” state and a remote switch is in a first position. The device is configured to send a second signal to the cutting tool indicating a request to cause the cutting tool to perform a cutting operation responsive to receiving information indicative of actuation of at least one button of a user interface of the device.

A trimming apparatus includes a trimmer head assembly and trimmer head frame portion. The trimmer head assembly including a first wheel, a second wheel, a drive motor coupled to the first wheel, the trimmer head assembly first and second wheels in frictional contact with each other and their rotation axis defining a non-zero camber angle. A trimming apparatus may include a plurality of trimmer head assemblies arranged in a grid, and include movable grid flap assemblies. A trimming apparatus may include a plurality of trimmer head assemblies formed and distributed as a drum module, or a plurality of drum modules. A trimming apparatus may include a single trimmer head assembly with a handle for manual operation.

Rotary knifes/cutters play an important role in manufacturing of finished products. The rotary cutters tend to lose their cutting material over time. Hence to compensate, pressure applied by cylinder over rotary cutter needs to be changed. But this change in pressure needs to be optimum as too high pressure can lead to loss of material and too low pressure can stop cutting operation. Present application provides methods and systems for real time estimation of pressure change requirements for rotary cutters. The system first determines minimum and maximum usage limit for rotary cutter based on historical rotary cutter usage data and real-time pressure value using first trained model. The system, upon determining that minimum usage limit is reached, determines time for next pressure change based on physical parameters using second trained model. Thereafter, system compares estimated time with estimated maximum usage limit and displays notification to change pressure based on comparison.

First scanned images of the first container are received from a scanning device that show the contents of the interior of the first container before the first container is cut and opened. Second scanned images that are of the contents of the first container after the first container is cut and opened are also received. The images are analyzed and, based upon the analysis, selective modifications to the operating parameters of the container opening machine are determined and made.

An apparatus includes channel assemblies in a rotatable section, a cutting assembly, a discharge assembly, and a cleanout assembly. The channel assembly holds a bulk instance of compressible material extending through upper and lower channels of a continuous channel. The cutting assembly moves in relation to the channel assembly to isolate the upper and lower channels, severing upper and lower material portions of the bulk instance. The discharge assembly directs gas into the lower channel of a channel assembly to discharge the lower material portion from the lower channel, based on radial alignment of a conduit assembly of the channel assembly with a conduit assembly of the discharge assembly. The cleanout assembly supplies a fluid through the conduit assembly of the channel assembly, based on radially alignment of the conduit assembly of the channel assembly with a conduit assembly of the cleanout assembly.

The swivel knife holder assembly includes a shoulder screw defining an axis, and having a proximal threaded end and a distal head, and mounted on the shoulder screw is a bobbin assembly. The swivel knife holder assembly also includes a shell defining an interior, and having a distal opening and a proximal opening. A core is secured in the interior and is coupled to a knife for cutting fabric material. The proximal opening of the shell is defined by a flange and houses the shoulder screw therein. Threadably coupled to the proximal threaded end of the shoulder screw is a stem. The stem secures the bobbin assembly within the shell and also includes a mounting surface for engaging a reciprocating drive mechanism.

A printing apparatus includes a cutter unit that includes a first blade that moves in a first direction from a standby position to a cutting position to cut a printing medium and a drive pin that moves integrally with the first blade, a drive cam which has a cylindrical shape and on a side surface of which a guide groove engaged with the drive pin is provided, and a driving motor that rotates the drive cam, in which, when the drive cam rotates, the guide groove guides, via the drive pin, the first blade in the first direction from the standby position to the cutting position.

A thermoforming packaging machine includes a forming station for thermoforming troughs in a film web, a filling path for filling products into the troughs, a sealing station for sealing the troughs, a chain guide for guiding a transport chain for the film web, a transverse cutting device for cutting the film web in a direction transverse to the transport direction, a longitudinal cutting device for cutting the film web in the transport direction, and a control device for controlling processes running on the thermoforming packaging machine. The transverse cutting device comprises a film punch, an adjustment drive which can be controlled by the control device for closing and opening the film punch, and a detection unit which is connected to the control device and which has at least one sensor which is configured to detect, per processing cycle, a force progression occurring at the film punch during opening and closing.
