Offset Book Block Bar for Uniform Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for temporarily storing loose book blocks before binding result in irregular pressing, leading to deformation and processing issues, as well as increased paper consumption and machine malfunctions due to inadequate alignment and adhesive application.
Innovation Solution
Forming bars by aligning book blocks with their folded edges as lower edges and offsetting them laterally, ensuring consistent pressing force and clear separation points, allowing for uniform pressing and easy separation during further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If loose book blocks are placed on pallets for temporary storage, then storage capability is improved, but pressing uniformity deteriorates
Solution Approach 1:
The invention segments the book blocks into a bar structure with individual book blocks offset relative to each other. This segmentation allows each book block to be pressed independently and uniformly against the pressing surface, eliminating the pressing variations that occur when stacks are placed on pallets. The offset arrangement ensures that pressing force is distributed evenly across all book blocks.
Solution Approach 2:
The invention transitions from a vertical stacking arrangement (book blocks stacked one on top of another on pallets) to a horizontal bar arrangement where book blocks are offset laterally. This dimensional change from vertical to horizontal arrangement enables uniform pressing across all book blocks while maintaining storage capability, as the bar can be stored horizontally in a compact manner.
2Ease of manufacture
If book blocks are pressed irregularly during storage, then storage simplicity is improved, but product quality deteriorates
Solution Approach 1:
By segmenting the book blocks into a bar structure with offset arrangements, the invention enables uniform pressing of each individual book block while maintaining simple storage. The segmented structure allows the pressing mechanism to apply force evenly to each segment without requiring complex storage infrastructure.
Solution Approach 2:
The bar structure with offset book blocks is designed to be self-pressing during storage. The offset arrangement naturally positions each book block to receive pressing force from the bar structure itself, eliminating the need for complex external pressing mechanisms while ensuring uniform pressing of all book blocks.
3Ease of operation
If adhesive is applied to printed sheets for separation, then separation capability is improved, but paper consumption increases
Solution Approach 1:
The invention extracts the separation function from adhesive application and replaces it with the mechanical offset arrangement of book blocks in the bar structure. The offset positions naturally create separation points between book blocks, eliminating the need for adhesive and subsequent cutting operations, thereby reducing paper consumption.
Solution Approach 2:
The invention converts the potential harm of adhesive application (increased paper consumption and processing complexity) into a benefit by using the offset bar structure to create natural separation points. The same offset arrangement that ensures uniform pressing also provides clear separation points for easy separation without requiring additional adhesive or cutting operations.
4Volume of stationary object
If book blocks are stacked without offset, then storage compactness is improved, but pressing uniformity deteriorates
Solution Approach 1:
The invention segments the stacked book blocks into a bar structure where each book block is offset relative to its neighbors. This segmentation maintains storage compactness while enabling uniform pressing, as each segmented book block can be pressed independently against the pressing surface without the pressing variations that occur in non-offset stacks.
Solution Approach 2:
The invention maintains vertical stacking compactness while adding horizontal offset positioning. This two-dimensional arrangement (vertical stack with horizontal offsets) achieves both compact storage and uniform pressing by distributing book blocks across multiple horizontal positions within the same vertical stack space.

AI summary
The method involves combining multiple printing sheets (10) to a book block (3-1 to 3-n) and compressing multiple book blocks with same orientation on the lower edges (7) of the printing sheet to a rod (13). A book block is offset parallel to the lower edges of the printing sheets and transverse to a height of the rod such that a side edge (17-1 to 17-n) of the book block protrudes opposite to a side edge of an adjacent book block. An independent claim is included for a rod with an information carrier.
