A protective guard for a hand, finger or thumb includes a first thermoplastic layer heat welded to second thermoplastic layer. The second thermoplastic layer has a thickness that is greater than the thickness of the first thermoplastic layer.

A production system of a water-absorbent core. The supplying component thereof is configured to convey the fluffy cotton to the starting end of the transmission component, and the plurality of outlets of the supplying component for conveying the mixture of the fluff pulp and the hot-melt fibers to the transmission component are all located in the middle portion of the transmission component, the feeding port for conveying the super absorbent polymer to the transmission component and the outlets are arranged alternately along the transmitting direction of the transmission component, and each feeding port is located between the two outlets; the vacuum adsorption device can cause the mixture to be absorbed on the transmission component; the hot air penetration device performs hot air penetration treatment on the laminate; and the ultrasonic cutting device of the slitting mechanism is configured to ultrasonically cut the laminate after the hot air penetration treatment.

Method and apparatus are disclosed for mechanically opening a heat-bonded connection site between two hollow, flexible, thermoplastic segments of a medical fluid flow path, the heat-bonded connection site having an axis. The connection site is compressed between two facing surfaces, and the facing surfaces are relatively moved to rotate the connection site about the connection site axis and to apply force to the connection site substantially perpendicular to the connection site axis.

A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.

A laminating device includes: a plurality of laminating heads that each holds a unit laminated body; a drum section in which the plurality of laminating heads are arranged, which holds each laminating head swingably via a support shaft, and which rotates to advance each laminating head to a laminating position facing a lamination stage; a cam section which is in contact with each laminating head and which causes each laminating head to swing around the support shaft in association with a movement of each laminating head caused by a rotation of the drum section; and a biasing member that biases each laminating head in a radial direction of the drum section.

A sealing and cutting device for forming bags containing products includes; a sonotrode for sealing a portion of a continuous tubular strip, feeding along a feed direction; a counterhead positioned facing the sonotrode; a movement system for moving the sonotrode and/or anvil between a first non-operating position, wherein the sonotrode and the anvil are apart, and a second operating position wherein the sonotrode and the anvil are in contact to simultaneously seal a head and bottom of respective bags. A cutting element includes a circular blade connected to a supporting and movement element which imparts a translational movement to the blade with a circular shape along a direction perpendicular to the feed direction of the strip. The anvil includes a slit from which the blade 6 protrudes, for cutting the strip, by contact with the sonotrode in the second operating position, to separate a bag formed from the remaining strip.

Provided is a tape pasting mechanism with multiple functions of clutch-type synchronous punching, tape pasting and cutting which belongs to a tape pasting device for foil and includes a linear drive module, a clutch module, and following modules that are moved by the linear drive module: a punching module, a tape pasting module and a cutting module. The punching module includes a punching needle. The clutch module includes a punching bottom die that mates with the punching needle for punching. The clutch module is movable on the linear drive module together with the punching module.
