Methods and devices for etching patterns on interior surfaces of hollow objects are described. The method may include preparation of the interior surface of the object, such as pre-cleaning, and coating the interior surface of the object. A pattern may then be generated on the interior surface of the object by any of mechanical or manual scribing and peeling, laser ablation, or photoresist coating and laser exposure, development and hardening. The pattern is then etched using chemical etchants, and finished to remove remaining coating, provide surface passivation and/or protectant application. Mechanical and laser devices which may facilitate pattern generation are also described.

A method for processing a thin film layer, for example to form an ink jet printhead, can include the use of an adhesive layer that can be converted from a first state having a first adhesive force to a second state having a second adhesive force, where the first state is stronger than the second state. Conversion from the first state to the second state can be performed using a suitable treatment. In an embodiment, the adhesive layer may be a thermal release material that is converted during a heat treatment. In another embodiment, the adhesive layer may be a layer that is sensitive to ultraviolet (UV) light, and is converted during exposure to UV light emitted by a UV light source.

A slit-cutting device includes a first holder, a second holder, a first contactable member a second contactable member, and a protrusion member. The first holder includes a medium faceable area and a first contactable member. The second holder holds a blade and includes a second contactable member. A cutting edge of the blade may cut a medium between the first holder and the blade. The first contactable member and the second contactable member contact each other and defined a closest approach distance between the cutting edge and the first holder. The closest approach distance is longer than zero and below a thickness of the medium. The protrusion member protrudes more than the closest approach distance from a part of the medium faceable area. The cutting edge may make a cut line includes at least a part of a slit-cut and a full-cut in a cutting edge direction in the medium.

A process is provided for making bulk textured material sheeting. As a continuous supply of flat material sheeting is fed, the sheeting is repeatedly impacted with toothed knives, each knife creating a row of raised and generally pointed structures on the sheeting to texture the sheeting.

A score die including a body with a generally planar first surface. The first surface includes a score blade. The score blade has a number of cutting portions, and, each cutting portion has a substantially uniform cross-section.

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

A device for machining distinctive marks on line includes a clamping positioning system and a mark machining system. The clamping positioning system includes a first frame, a clamping cylinder and a fixed roller are fixed on the first frame, and a clamping roller corresponding to the fixed roller is fixed to an output end of the clamping cylinder.

An apparatus for cutting capsules is disclosed as including an engaging portion rotatable together with a spindle, the engaging portion including an axially protruding projection for abutting on an inner protrusion of the cap in a circumferential direction, and a contact surface for abutting an inner central region of the cap, the contact surface and the abutting surface being movable to take a phased angular orientation configuration with respect to a cutting device for cutting caps and an axial holding configuration.

A cap is disclosed in which the inner protrusion has a preset angular position with respect to a circumferential score on a side wall of the cap.

A method for cutting a cap is disclosed including the steps of: leading the projection to a circumferential abutment on the protrusion, leading the contact surface to an axial abutment against the inner central region, and scoring the cap by means of the cutting device.
