A straw forming machine includes a feeding device, a pressing device, a sticking device, a conveyor device, and a cutting device. The paper material is stretched from the feeding device to the pressing device which curls the paper material. When the paper material is delivered to the sticking device, the two sides of the paper material are pressed by the sticking device to form the paper pipe, and the press roll of the sticking device rolls and sticks the two abutting portions of the paper pipe. Then, the paper pipe is delivered by the conveyor device to the cutting device which cuts the paper pipe to form drinking straws.

A method to enable formation of ornamental circlets, comprising: forming a band that comprises a first end, a second end, a first ornamental motif positioned adjacent to the first end, and a second ornamental motif positioned adjacent to the second end; forming a tab in the first end adjacent to the first ornamental motif; forming a notch in the first end adjacent to the tab; forming slits in the second end adjacent to the second ornamental motif, twisting the band longitudinally 360 degrees; passing the slits through the notch to position the first ornamental motif under the second ornamental motif; and positioning the second ornamental motif under the tab. Forming the tab comprises forming the tab to have longitudinal symmetrically along the band. Forming the notch comprises forming the notch to angularly extend from a periphery of the band to the tab.

A method and apparatus are provided for the manufacture of an article made up of a number of elements, including a resilient element, that are bonded together during the manufacturing process. The apparatus includes a guide track which defines a path along which the elements travel during the manufacturing process and a compression frame provided along at least part of the length of the track for compressing the resilient element as the resilient member travels along the path defined by the guide track. The process includes moving a combination of article precursor elements together along the guide track rails such that the compression frame acts to press the elements together during bonding. The method and apparatus minimize misalignment of the elements and thereby improve quality of the finished article as well increasing production rates compared to conventional methods and apparatus.

A sheet processing apparatus, including: a rotary member pair configured to nip a sheet conveyed in a conveyance path and rotate to fold the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path, the one rotary member including: a first part; and a second part, wherein a first distance between the first part and a rotary shaft center of the one rotary member is greater than a second distance between the second part and the rotary shaft center, and wherein the guide portion is positioned at a first position in case that the second part is positioned at a first rotational position, and the guide portion is positioned at a second position different from the first position in a distance from the rotary shaft center in case that the second part is positioned at a second rotational position.

A sheet processing apparatus, including: a conveyance path in which a sheet is conveyed in a predetermined conveyance direction; a rotary member pair configured to nip the sheet conveyed in the conveyance path and rotate to perform folding processing on the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path and configured to guide a downstream edge of a sheet conveyed in the predetermined conveyance direction, wherein, in case that a sheet is conveyed in the conveyance path in the predetermined conveyance direction, the guide portion guides a downstream edge of the sheet in the predetermined conveyance direction in a state in which the guide portion is held in contact with the one rotary member.

Apparatus (100; 200) for making straws comprising a support structure (60; 600) defining an internal volume and carrying a feeding station (30; 300) configured to feed a strip (1a) or at least one discrete sheet (1b) of paper material, and a forming station (10; 101) with a conveyor (13; 130) comprising a base (15; 150), a first side wall (16; 160) and a second side wall (17; 170) converging with each other. The conveyor is configured to receive the strip in a substantially flat form at an infeed portion and wind it around a winding axis to define a cylindrical body (5) made of paper material, wherein the strip edges (2, 3) are facing each other and overlapping to define a mutually overlapping portion (4). The apparatus further comprises a winding body (11; 110) passing through a passage opening (14; 140) of the conveyor, and a constraining station (20; 201) configured to join the strip edges to define a straw.

The invention relates to an assembly of a rolled-up sheet and a holder. The rolled-up sheet has edge regions which touch each other near a first pair of opposite edges, wherein a flat end region is formed. A curved center region is rolled around a longitudinal axis to form a rolled-up end region. The holder is provided with a first support surface for supporting the flat end region of the rolled-up sheet, and with a bearing part for supporting one of the first pair of opposite edges. The holder furthermore has a clamping part which can be fixed in a holding position with respect to the first support surface in which the rolled-up sheet can be clamped between the clamping part and the first support surface.
