Abstract:
An injection moulded, plastics material cap (1) for a screw top bottle has a top and a skirt with an anti-tamper band (2) connected to the skirt at a tear-off line by links (3). On the inside of the top of the cap, a depending annular ridge (10) is provided. Its inside diameter is such that it abuts and seals on the outside diameter of the distal end of neck of the bottle. Also on the inside of the cap, inside the ridge (10), is moulded a forked feature having an inner limb (12) which extends generally downwards with an outwards bias, and an outer limb (13) which extends generally outwards with downwards bias. The inner limb is dimensioned to fit inside the mouth at the neck of the bottle, sealingly engaging it, whilst the outer limb is dimensioned to abut the end of the neck, also sealingly engaging it when the cap is screwed tight. On the inside of the anti-tamper band, upwardly and inwardly extending tongues (21) are provided. Adjacent ones of these are interconnected by webs (20) in the form of invert V folds. The folds extend up and out (radially) from the tongues. The latter have ribs (22) on their outer faces. Above the proximal ends of the tongues, a ridge (23) is provided around the inside of the band, at a position such that the ribs abut it when the tongues are pushed up, as on screwing of the cap onto the bottle. The combined action of the folded webs (20) and the resilience of the tongues (21) themselves causes them to spring inwards when pushed outwards during fitting of the cap to the bottle. The abutment of the ribs (22) against the ridge (23) limits the outwards movement of the tongues.
Abstract:
A binding device, comprising a switching flapper (15) which switches a sheet feed route to either an upper sheet delivery port or a lower sheet delivery port, sheet feed rollers (20) installed at the upper sheet delivery port, a shutter (13) installed at the lower sheet feed port, a stapler (14), and sheet delivery rollers (12), wherein the sheet feed rollers (12) can feed sheets in the direction reverse to the normal sheet feed direction and, when the sheets are fed in a reverse direction, the shutter (13) stops the sheets at a specified position for positioning, the stapler (14) binds the positioned sheets, and the sheet delivery rollers (12) butt the sheets against the shutter (13), align them with each other and, after the sheets have been bound, delivers the sheets in the normal sheet feed direction, whereby the structure of the binding device can be simplified and the size of it can be reduced.
Abstract:
A system for the perfect binding of a book block (14) within a soft paper cover is disclosed in which the center portion (18) of the cover is sized relative to the thickness of the book to be bound. An activatable adhesive is applied to the inner surface of the center portion of the cover. The book block is inserted into the cover such that the spine (S) of the book block is generally in register with the adhesive. The cover is forcibly compressed onto the book block by pressing members (60a, 60b). An ultrasonic horn (66) is brought into forcible working engagement with the outer surface of the center portion of the cover and is rendered resonant so as to transmit ultrasonic energy to the adhesive sufficient to melt the adhesive and to force the adhesive into the edges of the pages of the book block along the spine and to force the pages of the book block into the adhesive along the center portion of the cove such that upon the cessation of the ultrasonic energy the adhesive hardens substantially instantaneously thus binding the cover to the book block. A method of binding a book is also disclosed.
Abstract:
A first pack of sheets (1) is placed on a conveyor line (2), and a welding operation (4) is carried out whereby two welding lines (5) which are symmetrical with respect to the transverse axis are made, all the sheets being joined together. A second pack of sheets (6) is then placed on the first welded pack of sheets and both packs are subjected to a new welding operation (7) which determines a single welding line (8) situated in correspondence to the transverse axis so that by gluing all the surfaces comprised between the welding lines (5) the assembly is joined to the covers (9). Obviously, more packs of sheets can be added, the welding between the packs being then made through parallel lines which remains concentric with respect to the transverse axis.
Abstract:
The claimed processing operation is used to process piece goods. Large numbers of at least similar objects are processed by feeding objects into the operation in streams (PS) of starting products (A), feeding the starting products and/or intermediate products in product streams (PS) to processing steps (7, 8, 12, 14, 15...) where they are processed and then carried away from the processing steps, and discharging the processed objects from the operation in streams of end products (EP). In the incoming and outgoing product streams individual products or product groups are conveyed in a sequence. At each processing step at least one property of a processed product or product group is changed. The claimed operation is charaterized by sequence changes (4, 5, 6, 10, 13, 16, 17...) in which the sequence of products or product groups can be changed by transferring products in or out or combinations of both. As a result, the processing steps can be linked to any degree of complexity and nevertheless the operation can be carried out with great flexibility. Sequence changes as well as at least some of the processing steps can then be controlled according to relevant properties of the incoming products or product groups and/or according to a predetermined sequence to be established.
Abstract:
Individual sheets of, for example, paper are coated by feeding the sheets in succession through a coating station (11) in which a primer material and a low adhesion backsize material are applied to opposite sides of the sheets. The sheets are then deposited on a conveyor so that they are overlapped to form a pseudo-web of sheets.
Abstract:
A debinding apparatus for inclusion in a machine (40) adapted to bind together sheets having first apertures longitudinally spaced along one edge. The machine (40) uses a first narrow thermoplastic strip having studs spaced complementary to the first apertures, and a second narrow strip having second apertures spaced complementary to the first apertures. The machine includes an assembly for forming heads on the ends of the studs including a plurality of fingers (91) for engaging the ends of the stud and a mechanism for actuating the fingers (91) from an inoperative to an operative position. The improvement to the machine (40) comprising a debinding apparatus which disengages the mechanism for actuating the fingers (91) so that after the cutting elements soften the heads the fingers (91) do not cool the heads, thereby facilitating separation of the narrow strips and sheets. A switch (148) initiates the debinding apparatus.
Abstract:
A ring binder cover (4) is composed of a pair of themoplastic sheets (20, 22) superimposed in edge-to-edge relation with a stiffener insert panel (23) disposed therebetween. The insert panel bears two parallel grooves (25, 27) which divide the insert into a spine zone (30) and two cover zones (24, 26). The material of the insert lying at the bottom of the grooves forms a pair of flexible strips (32, 34) which, combined with the adjacent portions of the cover sheets, form hinges between the spine and each cover. The peripheral edge portions (40) of the two thermoplastic sheets are sealed together and provide a sealed envelope for the stiffener insert which defines semi-rigid back and front cover panels of the binder, hingedly connected to a rigid spine. The insert can be provided with insert notches (370, 470, 570) at each end of each flexible strip to reduce outward protuberance of the peripheral edge at the hinge ends. At the mouth of each insert notch, the peripheral edge can carry straight across, or can follow inward toward the insert notch to form a seam notch, or can have a seam area which extends inward toward each insert notch. Another feature which can be incorporated into the ring binder concept of this invention is the idea of a curvable spine. The curvable spine idea involves providing one or more hinge-like spine grooves (641, 642, 643, 644) on the inside surface of the spine portion of the insert between the two hinge grooves. This allows the spine to flatten when the covers are open, but to curve about the longitudinal axis of the spine (concave on the inside and convex on the outside) when the covers are closed.

Abstract:
The use of types of paper which are difficult to process necessitates preparatory steps such as notching or roughing in order to ensure durable bonding. Conventional processes and devices generate unilateral forces transversely to the pile of sheets which affect the guiding of the pile of sheets, their subsequent gluing and the durability of the binding. These transverse forces can be compensated by the new process and the concrete device. A processing device uses at least two identical, counterrotating partial devices (I, II) with processing tools in such a manner that the components of force (QLi, QRi) produced transversely to the pile of sheets (10) by the two partial devices act in opposite directions and compensate the transverse forces.
